Overview

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build
their businesses. Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new
clients. We believe we deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer free and subscription products
that provide real estate professionals with access to transaction-ready consumers and help them enhance their online presence. In the six months ended June 30, 2012, we had 22.0 million monthly unique visitors. As of June 30, 2012, we had more
than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers.

We empower
consumers to make more informed housing decisions by delivering the inside scoop on homes, neighborhoods, and real estate professionals through an intuitive and engaging user experience. Our large, continually refreshed, and searchable
database contains more than 110 million properties, including 4.5 million homes for sale and rent. We supplement listings data with local information on schools, crime, and neighborhood amenities to provide unique insights into each community.
In addition, we harness rich, insightful user-generated content from our active community of contributors, which includes consumers, local enthusiasts, and real estate professionals. With more than 5 million unique user contributions, we believe we
have the largest collection of user-generated content on homes, neighborhoods, and real estate professionals.

We enable real
estate professionals to better promote themselves and their listings and connect with transaction-ready consumers through our online and mobile marketing products. Our free products allow real estate professionals to build their personal brand by
creating an online profile, contributing content to our marketplace, leveraging social media for endorsements, and establishing their presence through mobile features such as check-ins. Our subscription products enable real estate
professionals to increase their visibility, promote their listings in search results, target mobile users, and generate more highly qualified leads from our large audience of transaction-ready consumers. We believe that our audience is highly
motivated and ready to purchase homes, as supported by our surveys conducted between November 2011 and May 2012 in which 76% of over 290,000 respondents contacting real estate professionals through our marketplace indicated that they are planning to
move in the next six months, and in which almost half of over 210,000 respondents stated that they are pre-qualified for a mortgage. We believe that the combination of our compelling solution with our transaction-ready audience results in a high
return on investment for real estate professionals who purchase our subscription products.

We benefit from powerful network
effects and a vibrant user community. Consumers contribute content by posting questions, reviewing neighborhoods, and writing agent recommendations. Real estate professionals, seeking to connect with our consumers, engage in our community by sharing
local knowledge, answering consumers questions, and contributing content to our marketplace. The breadth and quality of user-generated content contributed to our marketplace has helped to build our brand, deepen the engagement of our existing
users, and attract more users.

We are a leading mobile platform for the home search process and mobile devices are
increasingly critical to consumers and real estate professionals. We have introduced iPhone, iPad, Android, and Kindle applications that provide tailored mobile experiences, which has led to rapid growth in mobile use of our solution. In the six
months ended June 30, 2012, we had over 4.3 million mobile monthly unique visitors, an increase of 176% over the same period in 2011. In addition, our mobile users are more likely than our web users to contact real estate professionals through our
marketplace.

Our online marketplace is experiencing rapid growth. Monthly unique visitors to our marketplace increased from
5.0 million in the six months ended June 30, 2009 to 22.0 million in the six months ended June 30, 2012, and our subscribers increased from 2,398 as of June 30, 2009 to 21,544 as of June 30, 2012. We generate revenue primarily
from sales of subscription products to real estate professionals. We also generate revenue from display advertising sold to leading real estate and consumer brand advertisers seeking to reach our attractive audience. In the years ended
December 31, 2009, 2010, and 2011, and the six months ended June 30, 2012, we generated revenue of $10.3 million, $19.8 million, $38.5 million, and $29.0 million, respectively. During the same period, we had net losses of $7.0 million,
$3.8 million, $6.2 million, and $7.6 million, respectively.

Industry and Challenges

The residential real estate industry, which we estimate accounts for more than a trillion dollars in annual spending in the United States,
is undergoing a profound transformation. Technology is changing the way that consumers search for homes and the way in which real estate professionals attract clients and build their businesses. In addition, the recent unprecedented downturn in the
housing market is causing real estate professionals to seek more effective ways to market themselves and achieve a greater return on their marketing investment. These trends present significant opportunities to capitalize on shifts in behavior.

Historically, consumers lacked readily available access to detailed and comprehensive information essential to making housing
decisions, relying instead on disparate sources of information such as real estate professionals, local newspapers, and word of mouth. Over time, more information has become available online and, as a result, the Internet has become a primary source
of research for housing decisions. According to a November 2011 survey by the National Association of Realtors, a trade organization for real estate professionals, 88% of home buyers used the Internet to research homes. Additionally, the use of
mobile devices for home searches has become more prevalent. According to a 2012 survey by The Real Estate Book, a real estate website, 52% of respondents reported using a mobile device to look for homes, with 85% of non-users stating that they would
consider using a mobile device for their next search.

As consumers increasingly research homes online, real estate
professionals are shifting their marketing expenditures online to reach prospective clients. While initially these real estate professionals focused their spending on email, search, and creating websites with listings, now these professionals are
increasingly using online real estate marketplaces to generate leads.

With technology driving the home search process online,
consumers, real estate professionals, and advertisers face distinct challenges. Consumers are challenged to effectively compile and use fragmented information, gain local insights, and obtain information on the go.Real estate professionals
are challenged to reach todays online consumers, target the right leads, manage their businesses while on the go, and optimize their marketing spend. Advertisers are challenged to efficiently reach the right consumers while maximizing the
effectiveness of their advertising.

We believe that there are significant opportunities to address the challenges faced by consumers, real estate professionals, and advertisers. Borrell Associates, Inc., an advertising research and
consulting firm, estimated in an August 2012 industry paper that $23.7 billion would be spent in 2012 on real estate-related marketing in the United States. According to a November 2011 survey by the National Association of Realtors, 88% of home
buyers used the Internet to research homes. However, according to the Borrell Associates report, only 55% of the real estate marketing dollars in the United States were projected to be spent online in 2012. We believe that there is a disconnect
between where marketing dollars are spent and where consumers research homes. Therefore, we expect that real estate-related marketing spend will continue to migrate online from traditional channels.

Large, continually refreshed, searchable database of homes for sale and rent. We provide consumers with access to a large, continually
refreshed, and searchable database of properties. We enable consumers to customize their searches with property-specific filters to obtain up-to-date listings that are rich with property facts, price, and sale data.



Trusted insights, social recommendations, and proprietary analytics that provide local context. We provide consumers with local insights,
critical to a successful home search, not available elsewhere on an easy to use and comprehensive basis. These insights include information about schools, crime, neighborhood amenities, and real estate professionals.



Anytime and anywhere access. Our marketplace is accessible anytime and anywhere on the web and on major mobile platforms. Since the introduction
of our first mobile application in 2008, mobile use of our marketplace has grown rapidly.

Key
benefits for real estate professionals



Broad reach to transaction-ready consumers. We provide real estate professionals the ability to connect with our large audience of
transaction-ready consumers at scale on the web and through our mobile applications. We believe that a large portion of consumers using Trulia do not use other real estate websites, and that this enables real estate professionals on Trulia to
effectively identify and market themselves to consumers that they cannot find anywhere else.



Products that boost presence and deliver high-quality leads. Our free products enable real estate professionals to create and manage an online
profile, promote their personal brand with consumers by contributing content to our marketplace, and leverage social media for endorsements. Our subscription products enable real estate professionals to boost their visibility, promote their listings
in search results, and generate more high-quality leads from potential home buyers.



Anytime and anywhere access to critical information and tools. We offer mobile applications designed specifically for real estate professionals
to take their business on the go. Using our mobile applications, real estate professionals can access critical information that they need to conduct their business, including listings details, contacts, driving directions, and local information
about neighborhoods.



Significant return on investment. We believe that our subscription products deliver a high return on investment to real estate professionals.

Attractive audience. We believe our audience is highly attractive to consumer brand advertisers. A substantial portion of our audience is either
college educated, has a household income above $75,000, or is in the 25 to 54 age group. U.S. consumers with these characteristics tend to spend more of their annual income on home maintenance, insurance, household furnishings, apparel and
services, and entertainment than the average consumer, according to the Bureau of Labor Statistics 2010 Consumer Expenditure Survey, which makes our audience attractive for consumer brand advertisers.



Display advertising products that efficiently reach target consumers. We enable our advertisers to reach segments of our audience that are
attractive to them. Advertisers benefit from improved reach, impact, relevancy, and measurement of their marketing campaigns in our marketplace.

Our Strengths

We believe that our competitive advantage reflects the
following strengths:



We deliver the inside scoop. We are one of the leading online real estate marketplaces and provide consumers with powerful tools and
unique content that together deliver valuable insights into homes, neighborhoods, and real estate professionals. For example, our crime heat maps provide consumers with a view into neighborhood safety and our Facebook integration gives consumers
recommendations on real estate professionals from people in their social network. Through our Trulia Voices forum, we also provide consumers with local content from our community of contributors, including consumers, local enthusiasts, and
real estate professionals.



Superior products and user experience. We believe we have the best products in the industry for consumers and real estate professionals. We
invest significant resources into technology development and product design to create a superior user interface that provides compelling features and rich functionality for our users.



Large, differentiated, transaction-ready audience. Our website and mobile applications have attracted 22.0 million monthly unique visitors in
the six months ended June 30, 2012 and, based on data from comScore, Inc., a marketing research company, a significant portion of our visitors do not visit our primary competitors websites. For instance, according to comScore, during each
month in 2011 and in each of the six months ended June 30, 2012, more than 50% of our audience did not visit Zillow.com. We believe that our audience is highly motivated and ready to purchase homes, as supported by our surveys conducted between
November 2011 and May 2012 in which 76% of over 290,000 respondents contacting real estate professionals through our marketplace are planning to move in the next six months, and in which almost half of over 210,000 respondents stated that they are
pre-qualified for a mortgage.



Strong mobile monetization. We believe that we are one of the few companies that is monetizing its mobile products at a higher rate than web
products. Since we launched our subscription product for mobile devices in May 2012, we have sold this product at prices that yield a higher average monthly revenue per subscriber than our subscription products that are not focused on mobile
devices. In addition, our users are more likely to contact real estate professionals through our mobile applications than our website.



Better ROI for real estate professionals. We believe our subscription products provide compelling value and a better return on investment than
other marketing channels. On average, paying subscribers receive more than five times the number of monthly leads compared to real estate professionals who only use our free products.

Powerful network effects driven by unique content. We benefit from a self-reinforcing network effect that helps build our brand, drives user
engagement in our marketplace, and attracts more users to our website and mobile applications. Consumers post questions in our marketplace, attracting real estate professionals who add more content by answering these questions, which in turn
attracts more consumers to our marketplace.



Big data and analytics platform. We employ proprietary advanced analytics and heuristics capabilities to aggregate, filter, and analyze large
amounts of data from disparate sources that we have cultivated over the years. Our expertise in handling large amounts of externally-sourced data and combining it with user activity data collected from our marketplace allows us to improve the user
experience by developing innovative new tools and new functionality.

Our Strategy

Our goal is to build the leading online real estate marketplace. We intend to focus on the following key strategies in pursuit of our
goal:



Expand our audience and increase user engagement. We intend to grow our large, transaction-ready audience by continuing to offer superior
products for consumers. We plan to continuously enhance and refresh our database of homes, partner with third parties to add new and relevant local content, and encourage our users to contribute useful content. We also plan to develop new features
and tools that deepen our users engagement with our website and mobile applications, and to promote and foster interaction in our vibrant user community.



Grow the number of real estate professionals in our marketplace. We intend to further penetrate the large base of more than 2.8 million real
estate professionals in the United States by communicating the value proposition of our free and subscription products, growing our audience of transaction-ready consumers, and creating additional products.



Increase revenue. We plan to increase our revenue by selling more subscription and advertising products and by optimizing our pricing.



Increase brand awareness. We have built a leading real estate and consumer brand with limited marketing spend to date. We plan to continue to
grow our brand by providing our users with superior and innovative products.



Pursue adjacent opportunities. We plan to pursue opportunities in a number of large adjacent markets, such as rentals, mortgages, home
improvement, and agent tools, and to expand our business internationally.

described below, together with all of the other information in this prospectus, before making a decision to invest in our common stock. Some of these risks are:

optimize the pricing of our products.



Advertisers may reduce or end their advertising spending with us or we may be unable to attract new advertisers.

We may not be able to obtain comprehensive and accurate real estate listing information.



We participate in a highly competitive market.

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price
range set forth on the cover page of this prospectus, would increase or decrease, as applicable, the cash and cash equivalents and short-term investments, working capital, total assets, and total stockholders equity (deficit) by $ 4.7
million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated underwriting discounts and commissions payable by us. An increase or decrease of
1.0 million shares in the number of shares offered by us would increase or decrease, as applicable, the cash and cash equivalents and short-term investments, working capital, total assets, and total stockholders equity (deficit) by $14.0
million assuming an initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions
payable by us.

We count a unique visitor the first time a computer or mobile device with a unique IP address accesses
our website or our mobile applications during a calendar month. If an individual accesses our website or mobile applications using different IP addresses within a given month, the first access by each such IP address is counted as a separate unique
visitor. We calculate our monthly unique visitors based on the monthly average over the applicable period. Our number of monthly unique visitors includes mobile monthly unique visitors.

Condition and Results of OperationsOverviewKey Business Metrics.

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United
States, or GAAP. We define Adjusted EBITDA as net loss adjusted to exclude interest income, interest expense, depreciation and amortization, change in fair value of warrant liability, and stock-based compensation. Below, we have provided a
reconciliation of Adjusted EBITDA to our net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of
financial performance calculated and presented in accordance with GAAP. Our Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in the same manner as
we calculate the measure.

We include Adjusted EBITDA in this prospectus because it is an important measure upon which our
management assesses our operating performance. We use Adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences primarily caused by
variations in capital structures, tax positions, the impact of depreciation and amortization expense on our fixed assets, changes related to the fair value remeasurements of our preferred stock warrant, and the impact of stock-based compensation
expense. Because Adjusted EBITDA facilitates internal comparisons of our historical operating performance on a more consistent basis, we also use Adjusted EBITDA for business planning purposes, to incentivize and compensate our management personnel,
and in evaluating acquisition opportunities. In addition, we believe Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of
financial performance and debt-service capabilities.

Our use of Adjusted EBITDA has limitations as an analytical tool, and
you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:



Adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments;

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and
Adjusted EBITDA does not reflect capital expenditure requirements for such replacements;

Adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our indebtedness;
and



Other companies, including companies in our industry, may calculate Adjusted EBITDA measures differently, which reduces their usefulness as a
comparative measure.

In evaluating Adjusted EBITDA, you should be aware that in the future we will incur
expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating
our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated:

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described
below, together with all of the other information in this prospectus, before making a decision to invest in our common stock. The risks and uncertainties described below may not be the only ones we face. If any of the risks actually occur, our
business, financial condition, operating results, and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment.

We have a limited operating history in an evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk
that we will not be successful.

We have a limited operating history in an evolving industry that may not develop as
expected. Assessing our business and future prospects is challenging in light of the risks and difficulties we may encounter. These risks and difficulties include our ability to:



increase the number of consumers using our website and mobile applications;



continue to obtain home listing information, as well as information on schools, crime, and neighborhood amenities;



increase the number of real estate professionals subscribing to our products;

successfully compete with other companies that are currently in, or may in the future enter, the business of providing residential real estate
information online and on mobile applications, as well as with companies that provide this information offline;



successfully compete with existing and future providers of other forms of offline, online, and mobile advertising;



successfully navigate fluctuations in the real estate market;



effectively manage the growth of our business;



successfully expand our business into adjacent markets, such as rentals, mortgages, and home improvement; and



successfully expand internationally.

If the demand for residential real estate information online does not develop as we expect, or if we fail to address the needs of consumers, real estate professionals, or advertisers, our business will be
harmed. We may not be able to successfully address these risks and difficulties, which could harm our business and cause our operating results to suffer.

We have a history of losses and we may not achieve or maintain profitability in the future.

We have not been profitable on a quarterly or annual basis since we were founded, and as of June 30, 2012, we had an accumulated deficit of $43.8 million. We expect to make significant future
investments in the development and expansion of our business which may not result in increased revenue or growth. In addition, as a public company, we will incur significant legal, accounting, and other expenses that we did not incur as a private
company. As a result of these increased expenditures, we will have to generate and sustain increased revenue to achieve and maintain future profitability. While our revenue has grown in recent periods, this growth

may not be sustainable and we may not achieve sufficient revenue to achieve or maintain profitability. We may incur significant losses in the future for a number of reasons, including slowing
demand for our products, increasing competition, weakness in the residential real estate market, as well as other risks described in this prospectus, and we may encounter unforeseen expenses, difficulties, complications and delays, and other unknown
factors. Accordingly, we may not be able to achieve or maintain profitability and we may continue to incur significant losses in the future, and this could cause the price of our common stock to decline.

If real estate professionals do not continue to subscribe to our products, or we are unable to attract new subscribers, our business and operating
results would be harmed.

We rely on subscriptions purchased by real estate professionals to generate a substantial
portion of our revenue. Subscriptions accounted for 32%, 47%, 58%, and 68% of our revenue in 2009, 2010, 2011, and the six months ended June 30, 2012, respectively. We generally offer subscriptions for periods between one month to 12 months, with
most real estate professionals preferring to subscribe for periods shorter than 12 months.

Our ability to attract and retain
real estate professionals as subscribers, and to generate subscription revenue, depends on a number of factors, including:

A key focus of our sales and marketing activities has been to further penetrate the large base of more than 2.8 million real estate professionals in the United States. As of June 30, 2012, we had more
than 360,000 active real estate professionals in our marketplace, and 21,544 total subscribers. We spend a considerable portion of our operating expenses on sales and marketing activities. Our sales and marketing expenses were our largest operating
expenses in 2011 and the six months ended June 30, 2012. Sales and marketing expenses reflect many of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing expenses will
continue to increase in absolute dollars as we seek to grow the number of subscribers in our marketplace. If we are unable to increase the number of total subscribers in our marketplace, our revenue may not grow and our operating results could
suffer.

Real estate professionals may not continue to subscribe with us if we do not deliver a strong return on their
investment in subscriptions, and we may not be able to replace them with new subscribers. In addition, real estate professionals sometimes do not renew their subscriptions with us because of dissatisfaction with our service. If subscribers do not
renew their subscriptions with us with the same or higher subscription fees, or at all, or we are unable to attract new subscribers, our business and operating results would be harmed.

Further, although a majority of our revenue in 2011 and the six months ended June 30, 2012 was generated from subscriptions purchased by
real estate professionals, we cannot be certain that subscribers will renew their subscriptions with us and that we will be able to achieve the same or higher amounts of subscription revenue in the future. Historically, we have not focused on
renewal rate as an important metric for our business. Moreover, we believe renewal rate may be a misleading metric for our business as a result of seasonality, the fact that many real estate professionals only purchase subscriptions for a limited
period of time as part of their advertising campaigns, and other factors.

In addition, if we need to reduce our subscription fees due to competition, our business,
operating results, financial condition, and prospects would suffer if we are unable to offset any reductions in our fees by increasing our number of consumers and advertisers, reducing our costs, or successfully developing and deploying new features
on a timely basis.

If we are not able to optimize our pricing and increase our average revenue per subscriber, we may not be able to
grow our revenue over time.

Our ability to grow revenue depends, in part, on our ability to optimize pricing and
increase average monthly revenue per subscriber over time. Since launching our first subscription product in 2007, we have continued to expand our products and optimize pricing of our products. In 2009, 2010, 2011, and the six months ended
June 30, 2012, our average monthly revenue per subscriber was $47, $80, $110, and $140, respectively. As we continue to optimize our pricing, real estate professionals may not accept these new prices, which may harm our business and growth
prospects.

If advertisers reduce or end their advertising spending with us, or if we are unable to attract new advertisers, our business
and operating results would be harmed.

Display advertising accounted for 68%, 53%, 42%, and 32% of our revenue in
2009, 2010, 2011, and the six months ended June 30, 2012, respectively. Our advertisers can generally terminate their contracts with us at any time or on very short notice. Our ability to attract and retain advertisers, and to generate
advertising revenue, depends on a number of factors, including:



the number of consumers using our website and mobile applications;



our ability to continue to attract an audience that advertisers find attractive;

our ability to deliver an attractive return on investment to advertisers.

We may not succeed in capturing more spending from advertisers if we are unable to demonstrate to advertisers the effectiveness of
advertising in our marketplace as compared to alternatives, including traditional offline advertising media such as newspapers and magazines.

If advertisers reduce or terminate their advertising spending with us and we are unable to attract new advertisers, our revenue, business, operating results, and financial condition would be harmed. For
example, although we experienced sequential increases in media revenue during each of the eight quarters ended December 31, 2011, the growth in our media revenue slowed during the year ended December 31, 2011 and our media revenue
decreased in the three months ended March 31, 2012 relative to the three months ended December 31, 2011. The primary reason for the decrease in media revenue during the three months ended March 31, 2012 was the loss of a significant customer which
declared bankruptcy. In our display advertising business, we also have a limited ability to replace the loss of revenue resulting from the loss of a customer during a particular quarter because of the significant time required to secure an
alternative advertiser for such advertising inventory, run the alternative advertising campaign on our marketplace, and satisfy our revenue recognition criteria from such campaign. As a result, the loss of a customer during a quarter could result in
our inability to replace the lost revenue from such customer within that quarter and, therefore, we will sometimes encounter variances in our media revenue.

If we cannot obtain comprehensive and accurate real estate listing information, our business will suffer.

Our offerings are based on receiving current and accurate real estate listing data. We depend on, and expect to continue to depend on, relationships with various third parties to provide this data to us,
including real estate listing aggregators, multiple listing services, real estate brokerages, apartment management companies, and other

third parties. Many of our agreements with our listing sources are short-term agreements that may be terminated with limited or no notice. If our relationship with one or more of these parties is
disrupted, the quality of the experience we provide to users would suffer.

We currently depend on a listing aggregator to
provide us with a substantial portion of the unique listings in our database. While these listings are available from their original sources, it would take substantial time and effort for us to aggregate these listings from all of the original
sources. Therefore, if the agreement with our largest listing aggregator is terminated, we may not be able to fully replace the listings in a timely manner or on terms favorable to us, or at all, which would adversely affect our business and
operating results. In addition, as real estate brokers typically control the distribution and use of their listings, our business could suffer if real estate brokers withheld their listings from us. From time to time in the past, real estate brokers
have refused to syndicate their listings to us, and we cannot assure you this will not happen in the future. If real estate brokers refuse to syndicate listings to us, the quality of our products would suffer due to the decline of timely and
accurate information, which could adversely affect our business and operating results.

If use of our mobile products does not continue
to grow or we are not able to successfully monetize them as we expect, our operating results could be harmed and our growth could be negatively affected.

Our future success depends in part on the continued growth in the use of our mobile products by our users and our ability to monetize them. During 2011 and in the six months ended June 30, 2012, our
mobile products accounted for 14% and 20% of our total traffic, respectively. We currently monetize our mobile offerings through our Trulia Mobile Ads subscription product for real estate professionals and through our mobile website,
m.trulia.com. We monetize our mobile applications principally through our Trulia Mobile Ads subscription product through which real estate professionals can purchase local advertising on our mobile applications and our mobile website by zip
code or city and by share of a given market. We monetize our mobile website through the sale of display advertisements and we also provide our subscribers rotational placement in a local lead form that appears on certain pages of our mobile website.
The use of mobile technology may not continue to grow at historical rates, and consumers may not continue to use mobile technology for real estate research. Further, mobile technology may not be accepted as a viable long-term platform for a number
of reasons, including actual or perceived lack of security of information and possible disruptions of service or connectivity. In addition, traffic on our mobile applications may not continue to grow if we do not continue to innovate and introduce
enhanced products on mobile platforms, or if users believe that our competitors offer superior mobile products. The growth of traffic on our mobile products may also slow or decline if our mobile applications are no longer compatible with operating
systems such as iOS or Android or the devices they support. Additionally, real estate professionals and advertisers may choose to devote less of their spending to target mobile users for a number of reasons, including a perceived lack of
effectiveness of display advertising on mobile devices. Although we have seen strong results in our mobile product monetization efforts with the launch of Trulia Mobile Ads in May 2012, these are early results with only a few months of data
and we cannot assure you that we will continue to monetize our mobile products as effectively in the future. If use of our mobile products does not continue to grow, or if real estate professionals or advertisers decrease their spending on our
mobile products, our business and operating results could be harmed.

If we do not continue to innovate and provide useful products, we
may not remain competitive, and our business and financial performance could suffer.

Our success depends in part on
our ability to continue to innovate. This is particularly true with respect to mobile applications, which are increasingly being used by our audience. Our competitors regularly enhance their offerings and create new offerings for consumers, real
estate professionals, and others involved in the residential real estate industry. If we are unable to continue to offer innovative products or to keep pace with our competitors offerings, our business and operating results will suffer.

We rely on Internet search engines to drive traffic to our website, and if we fail to appear high up
in the search results, our traffic would decline and our business would be adversely affected.

We depend in part on
Internet search engines, such as Google, Bing, and Yahoo!, to drive traffic to our website. For example, when a user types a physical address into a search engine, we rely on a high organic search ranking of our webpages in these search results to
refer the user to our website. However, our ability to maintain high organic search result rankings is not within our control. Our competitors search engine optimization, or SEO, efforts may result in their websites receiving a higher search
result page ranking than ours, or Internet search engines could revise their methodologies in a way that would adversely affect our search result rankings. If Internet search engines modify their search algorithms in ways that are detrimental to us,
or if our competitors SEO efforts are more successful than ours, overall growth in our user base could slow. Search engine providers could provide listings and other real estate information directly in search results or choose to align with
our competitors. Our website has experienced fluctuations in search result rankings in the past, and we anticipate similar fluctuations in the future. Any reduction in the number of users directed to our website through search engines could harm our
business and operating results.

Our recent revenue growth rates may not be indicative of our future growth, and we may not continue to
grow at our recent pace, or at all.

From 2007 to 2011, our revenue grew from $1.7 million to $38.5 million, which
represents a compounded annual growth rate of approximately 119%. In the future, our revenue may not grow as rapidly as it has over the past several years. For instance, while our media revenue grew more rapidly in the year ended December 31, 2011
than the year ended December 31, 2010, our media revenue grew more slowly in the six months ended December 31, 2011 than it did in the six months ended June 30, 2011. We believe that our future revenue growth will depend, among other factors, on our
ability to:

attract a growing number of users to our website and mobile applications;



increase our brand awareness;



successfully develop and deploy new products for the residential real estate industry;



maximize our sales personnels productivity;



respond effectively to competitive threats;



successfully expand our business into adjacent markets, such as rentals, mortgages, and home improvement; and



successfully expand internationally.

We may not be successful in our efforts to do any of the foregoing, and any failure to be successful in these matters could materially and adversely affect our revenue growth. You should not consider our
past revenue growth to be indicative of our future growth.

Our revenue and operating results could vary significantly from period to
period, which could cause the market price of our common stock to decline.

We generate revenue through sales of
subscriptions to real estate professionals and sales of display advertising to advertisers. Our subscription and advertising sales can be difficult to predict and may result in fluctuations in our revenue from period to period. Our revenue and
operating results have fluctuated in the past, and may continue to fluctuate in the future, as a result of a variety of factors, many of which are outside of our control. As a result, comparing our revenue and operating results on a period-to-period
basis may not be meaningful, and you should not rely on past results as an indication of future performance.

fluctuations in user activity on our website and mobile applications, including as a result of seasonal variations;



competition and the impact of offerings and pricing policies of our competitors;



the effects of changes in search engine placement and prominence of our website;



the amount and timing of operating expenses related to the maintenance and expansion of our business, operations, and infrastructure;



our ability to control costs, particularly those of third-party data providers;



our ability to reduce costs in a given period to compensate for unexpected shortfalls in revenue;



the timing of costs related to the development or acquisition of technologies or businesses;



our inability to complete or integrate efficiently any acquisitions that we may undertake;



our ability to collect amounts owed to us from advertisers;



changes in our tax rates or exposure to additional tax liabilities;



claims of intellectual property infringement against us and any resulting temporary or permanent injunction prohibiting us from selling our products or
requirements to pay damages or expenses associated with any of those claims;



our ability to successfully expand in existing markets and enter new markets;



our ability to keep pace with changes in technology;



changes in government regulation affecting our business;



the effectiveness of our internal controls;



conditions in the real estate market; and



general economic conditions.

For example, individuals hired to join our sales team typically do not reach their maximum productivity until they have been employed for several months or more. Our fixed expenses related to the addition
of personnel may not result in an increase in revenue in a given period or at all.

As a result of the foregoing factors and
others discussed in this Risk Factors section, our operating results in one or more future periods may fail to meet or exceed our projections or the expectations of securities analysts or investors. In that event, the trading price of
our common stock would likely decline.

We generally experience seasonality in subscription revenue and display advertising due to fluctuations in traffic to
our website and mobile applications. During the fourth quarter of each year, traffic to our marketplace has historically declined and our revenue has historically grown more slowly than in other quarters. Conversely, we typically experience higher
growth in traffic and revenue during the spring and summer months, when consumers are more likely to buy new homes. We expect that seasonality will continue to affect traffic in our marketplace, as well as our revenue from subscriptions and
advertising.

Our business and financial performance are affected by the health of, and changes to, the residential
real estate industry. Although we have built and grown our business during a worldwide economic downturn, home-buying patterns are sensitive to economic conditions and tend to decline or grow more slowly during these periods. A decrease in home
purchases could lead to reductions in user traffic, reductions in subscriptions by real estate professionals, and a decline in marketing spend. Furthermore, online advertising products may be viewed by some existing and potential advertisers on our
website and mobile applications as a lower priority, which could cause advertisers to reduce the amounts they spend on advertising, terminate their use of our products, or default on their payment obligations to us. In addition, we may become
subject to rules and regulations in the real estate industry that may restrict or complicate our ability to deliver our products. These changes would harm our business and operating results.

Most recently, beginning in 2008, domestic and global economic conditions deteriorated rapidly, resulting in a dramatic slowdown in the
housing market, which slowed advertising spending in the real estate industry. In addition, changes to the regulation of the real estate industry and related areas, including mortgage lending and the deductibility of home mortgage interest, may
negatively affect the prevalence of home purchases. Real estate markets also may be negatively impacted by a significant natural disaster, such as earthquake, fire, flood, or other disruption. Declines or disruptions in the real estate market or
increases in mortgage interest rates could reduce demand for our products and could harm our business and operating results.

We
participate in a highly competitive market, and pressure from existing and new companies may adversely affect our business and operating results.

The market to provide home listings and marketing services for the residential real estate industry is highly competitive and fragmented. Homes are not typically marketed exclusively through any single
channel. Consumers can access home listings and related data through more than one source. Accordingly, current and potential competitors could aggregate a set of listings similar to ours. We compete with online real estate marketplaces, such as
Zillow and Realtor.com, other real estate websites, and traditional offline media. We compete to attract consumers primarily on the basis of the number and quality of listings; user experience; the breadth, depth, and relevance of insights and other
content on homes, neighborhoods, and professionals; brand and reputation; and the quality of mobile products. We compete to attract real estate professionals primarily on the basis of the quality of the website and mobile products, the size and
attractiveness of the consumer audience, the quality and measurability of the leads we generate, the perceived return on investment we deliver, and the effectiveness of marketing and workflow tools. We also compete for advertisers against other
media, including print media, television and radio, social networks, search engines, other websites, and email marketing. We compete primarily on the basis of the size and attractiveness of the audience; pricing; and the ability to target desired
audiences.

Many of our existing and potential competitors have substantial competitive advantages, such as:



greater scale;



stronger brands and greater name recognition;



longer operating histories;



more financial, research and development, sales and marketing, and other resources;



more extensive relationships with participants in the residential real estate industry, such as brokers, agents, and advertisers;

The success of our competitors could result in fewer users visiting our website and mobile
applications, the loss of subscribers and advertisers, price reductions for our subscriptions and display advertising, weaker operating results, and loss of market share. Our competitors also may be able to provide users with products that are
different from or superior to those we can provide, or to provide users with a broader range of products and prices.

We
expect increased competition if our market continues to expand. In addition, current or potential competitors may be acquired by third parties with greater resources than ours, which would further strengthen these current or potential competitors
and enable them to compete more vigorously or broadly with us. If we are not able to compete effectively, our business and operating results will be materially and adversely affected.

If our users do not continue to contribute content or their contributions are not valuable to other users, our marketplace would be less attractive, which could negatively affect our unique visitor
traffic and revenue.

Our success depends on our ability to provide consumers with the information they seek, which in
turn depends in part on the content contributed by our users. We believe that one of our primary competitive advantages is the quality and quantity of the user-generated content in our marketplace, and that information is one of the main reasons
consumers use our platform. If we are unable to provide consumers with the information they seek because our users do not contribute content, or because the content that they contribute is not helpful and reliable, the number of consumers visiting
our website and mobile applications may decline. If we experience a decline in consumers visiting our website and using our mobile applications, real estate professionals and advertisers may not view our marketplace as attractive for their marketing
expenditures, and may reduce their spending with us. Any decline in visits to our website and usage of mobile applications by consumers and any decline in spending by real estate professionals and advertisers with us would harm our business and
operating results.

In addition, we monitor new contributions to user-generated content because we believe this metric is a
key indicator of our user engagement and the strength of our community. In the event that the number of new contributions to user-generated content declines, this metric may provide a leading indicator of the health of our business. However, if the
quantity of new contributions to user-generated content continues to increase but the quality of user-generated content declines, this metric would not capture any corresponding declines in user engagement or the strength of our community as
evidenced by the lower quality of user-generated content, and such data would be of limited use in those circumstances.

Our growth
depends in part on our relationship with third parties to provide us with local information.

Third parties provide us
with information that we use to provide users with insights that go beyond listings, such as information about schools, crime, and neighborhood amenities. Property descriptions and sale transactions obtained via third-party data providers also
inform the valuations provided by our Trulia Estimates feature. If these third-party data providers terminate their relationships with us, the information that we provide to users may be limited or the quality of the information may suffer.
If we are unable to renew our agreements with these data providers on favorable terms to us or to secure alternative sources for this information, our costs may increase and our business may be harmed.

If we do not display accurate and complete information on a timely basis, our user traffic may decline, our reputation would suffer, and our
business and operating results would be harmed.

We receive listing and other information provided by listing
aggregators and other third parties that we include on our website and mobile applications. Our reputation with consumers depends on the accuracy and completeness of the information that we provide, although the accuracy and completeness of this
data is often outside of our control. We cannot independently verify the accuracy or completeness of all of the information provided to us by third parties. If third parties provide us with inaccurate or incomplete information that we then display
on our website and mobile applications, consumers may become dissatisfied with our products, our

traffic may decrease, and our reputation may suffer. Real estate professionals also expect listings data and other information to be accurate and complete, and to the extent our information is
incorrect or incomplete, our reputation and business relationships may suffer.

In addition, we update the listing information
that we provide on our website and mobile applications on a daily basis. To the extent that we are no longer able to update information in our marketplace on a timely basis, or if consumers begin to expect updates in a more timely manner, we may be
forced to make investments which allow us to update information with higher frequency. There can be no assurance that we will be able to provide information at a pace necessary to satisfy consumers in a cost-effective manner, or at all.

Growth of our business will depend on a strong brand, and any failure to maintain, protect, and enhance our brand would hurt our ability to retain
or expand our base of users, or our ability to increase their level of engagement.

We believe that a strong brand is
necessary to continue to attract and retain consumers and, in turn, the real estate professionals and others who choose to advertise on our websites and mobile applications. We need to maintain, protect, and enhance the Trulia brand in
order to expand our base of users and increase their engagement with our website and mobile applications. This will depend largely on our ability to continue to provide high-value, differentiated products, and we may not be able to do so
effectively. While we may choose to engage in a broader marketing campaign to further promote our brand, this effort may not be successful. Furthermore, negative publicity about our company, including our content, technology, sales practices,
personnel, or customer service could diminish confidence in and the use of our products, which could harm our operating results. If we are unable to maintain or enhance user and advertiser awareness of our brand cost effectively, our business,
operating results, and financial condition could be harmed. In addition, our website serves as a forum for expression by our users, and if some of our users contribute inappropriate content and offend other users, our reputation could be harmed.

We rely on a small number of advertising partners for a substantial portion of our media revenue, and we are subject to risks as a
result of this advertiser concentration.

In each of the years ended December 31, 2010 and 2011, the ten largest
advertising partners for the respective period accounted for more than 50% of our media revenue. For the six months ended June 30, 2012, the ten largest advertising partners in that period accounted for more than 60% of our media revenue. One of our
growth strategies is to increase the amount large advertisers spend in our marketplace, and we expect this revenue concentration to continue. If one or more of these large advertisers were to decrease or discontinue advertising with us, our business
and operating results will be adversely affected.

Our operating results may be adversely affected by a failure to collect amounts owed
to us by advertisers.

We often run display advertisements in our marketplace prior to receiving payment from an
advertiser, which makes us subject to credit risks. In the past, certain advertisers have been unable to pay us due to bankruptcy or other reasons, and we cannot assure you that we will not experience collection issues in the future. If we have
difficulty collecting amounts owed to us by advertisers, or fail to collect these amounts at all, our results of operations and financial condition would be adversely affected.

We depend on our talented personnel to grow and operate our business, and if we are unable to hire, retain, manage, and motivate our personnel, or if our new personnel do not perform as we
anticipate, we may not be able to grow effectively.

Our future success will depend upon our continued ability to
identify, hire, develop, motivate, and retain talented personnel. We may not be able to retain the services of any of our employees or other members of senior management in the future. We do not have employment agreements other than offer letters
with any key employee,

and we do not maintain key person life insurance for any employee. In addition, from time to time, there may be changes in our senior management team that may be disruptive to our business. If
our senior management team fails to work together effectively and to execute our plans and strategies, our business could be harmed.

Our growth strategy also depends on our ability to expand our organization by hiring high-quality personnel. Identifying, recruiting, training, integrating, managing, and motivating talented individuals
will require significant time, expense, and attention. Competition for talent is intense, particularly in the San Francisco Bay Area, where our headquarters is located. If we are not able to effectively recruit and retain our talent, our business
and our ability to achieve our strategic objectives would be harmed.

Growth may place significant demands on our management and our
infrastructure.

We have experienced substantial growth in our business that has placed, and may continue to place,
significant demands on our management and our operational and financial infrastructure. As our operations grow in size, scope, and complexity, we will need to improve and upgrade our systems and infrastructure. The expansion of our systems and
infrastructure will require us to commit substantial financial, operational, and technical resources in advance of an increase in the volume of business, with no assurance that the volume of business will increase. Continued growth could also strain
our ability to maintain reliable service levels for our users and advertisers, develop and improve our operational, financial, and management controls, enhance our reporting systems and procedures, and recruit, train, and retain highly skilled
personnel.

Our products are accessed by a large number of users often at the same time. If the use of our marketplace
continues to expand, we may not be able to scale our technology to accommodate increased capacity requirements, which may result in interruptions or delays in service. The failure of our systems and operations to meet our capacity requirements could
result in interruptions or delays in service or impede our ability to scale our operations.

Managing our growth will require
significant expenditures and allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as it grows, our business, operating results, and financial condition would be harmed.

A significant disruption in service on our website or of our mobile applications could damage our reputation and result in a loss of users of our
products and of advertisers, which could harm our business, operating results, and financial condition.

Our brand,
reputation, and ability to attract users and advertisers depend on the reliable performance of our network infrastructure and content delivery. We may experience significant interruptions with our systems in the future. Interruptions in these
systems, whether due to system failures, computer viruses, or physical or electronic break-ins, could affect the security or availability of our products on our website and mobile applications, and prevent or inhibit the ability of users to access
our products. Problems with the reliability or security of our systems could harm our reputation, result in a loss of users of our products and of advertisers, and result in additional costs.

Substantially all of the communications, network, and computer hardware used to operate our website and mobile applications is located at
a single colocation facility in Santa Clara, California. While we have made investments to back up our system in the event of a disruption involving this facility, our systems are not fully redundant. In addition, we do not own or control the
operation of this facility. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses,
earthquakes, and similar events. The occurrence of any of these events could result in damage to our systems and hardware or could cause them to fail.

Problems faced by our third-party web hosting providers could adversely affect the experience of our users. Our third-party web hosting providers could close their facilities without adequate notice. Any
financial difficulties, up to and including bankruptcy, faced by our third-party web hosting providers or any of the service

providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party web hosting providers are unable to keep
up with our growing capacity needs, our business could be harmed.

Any errors, defects, disruptions, or other performance or
reliability problems with our network operations could cause interruptions in access to our products as well as delays and additional expense in arranging new facilities and services and could harm our reputation, business, operating results, and
financial condition.

Our failure to protect confidential information of our users against security breaches could damage our reputation
and brand and harm our business and operating results.

We maintain sensitive information provided by users and
advertisers. We rely on encryption and authentication technology licensed from third parties to effect secure transmission of confidential information, including personally identifiable information and credit card numbers. We may need to expend
significant resources to protect against security breaches or to address problems caused by breaches. If we are unable to maintain the security of confidential information that is provided to us by our users, our reputation and brand could be harmed
and we may be exposed to a risk of loss or litigation and possible liability, any of which could harm our business and operating results.

Our business depends on our intellectual property, the protection of which is crucial to the success of our business. We rely on a
combination of patent, trademark, trade secret, and copyright law and contractual restrictions to protect our intellectual property. In addition, we attempt to protect our intellectual property, technology, and confidential information by requiring
our employees and consultants to enter into confidentiality and assignment of inventions agreements and third parties to enter into nondisclosure agreements. These agreements may not effectively prevent unauthorized use or disclosure of our
confidential information, intellectual property, or technology and may not provide an adequate remedy in the event of unauthorized use or disclosure of our confidential information, intellectual property, or technology. Despite our efforts to
protect our proprietary rights, unauthorized parties may attempt to copy aspects of our website features, software, and functionality or obtain and use information that we consider proprietary.

We have registered Trulia as a trademark in the United States, the European Union and Canada. Competitors may adopt service
names similar to ours, thereby harming our ability to build brand identity and possibly leading to user confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or
trademarks that incorporate variations of the term Trulia.

We currently hold the Trulia.com Internet
domain name and various other related domain names. The regulation of domain names in the United States is subject to change. Regulatory bodies could establish additional top-level domains, appoint additional domain name registrars, or modify the
requirements for holding domain names. As a result, we may not be able to acquire or maintain all domain names that use the name Trulia.

Litigation or proceedings before the U.S. Patent and Trademark Office or other governmental authorities and administrative bodies in the United States and abroad may be necessary in the future to enforce
our intellectual property rights, to protect our patent rights, trade secrets, and domain names and to determine the validity and scope of the proprietary rights of others. Our efforts to enforce or protect our proprietary rights may be ineffective
and could result in substantial costs and diversion of resources, which could harm our business and operating results.

Intellectual
property infringement assertions by third parties could result in significant costs and harm our business and operating results.

Other parties have asserted, and may in the future assert, that we have infringed their intellectual property rights. Such litigation may involve patent holding companies or other adverse patent owners
who have no relevant product revenue, and therefore our own issued and pending patents may provide little or no deterrence.

We could also be required to pay damages in an unspecified amount. For example, in September 2011, we entered into a settlement agreement with CIVIX-DDI LLC, or CIVIX, relating to a claim by
CIVIX that we infringed two CIVIX patents relating to searching and locating real estate. Under the settlement agreement, we agreed to pay CIVIX to settle the litigation.

In addition, on September 12, 2012, Zillow, Inc., or Zillow, filed a lawsuit against us in the United States District Court for the Western District of Washington, alleging that we infringe on one U.S.
patent held by it. The lawsuit alleges that one component of our Trulia Estimates feature infringes upon Zillows patent insofar as Trulia Estimates allows homeowners to claim their homes and provide additional information about
the properties, which enables us to update the valuation estimates for such properties. We started offering our Trulia Estimates feature in 2011. Zillow is seeking declaratory judgment that its patent is valid and enforceable, a permanent
injunction against the alleged infringement, compensatory damages, and attorneys fees. This litigation could cause us to incur significant expenses and costs. In addition, the outcome of any litigation is inherently unpredictable, and as a
result of this litigation, we may be required to pay damages; an injunction may be entered against us that requires us to change our Trulia Estimates feature; or a license or other right to continue to deliver an unmodified version of
Trulia Estimates may not be made available to us at all or may require us to pay ongoing royalties and comply with unfavorable terms. Any of these outcomes could harm our business. Even if we were to prevail, this litigation could be costly
and time-consuming, could divert the attention of our management and key personnel from our business operations, and may discourage consumers, real estate professionals, and advertisers from using our marketplace.

Furthermore, we cannot predict whether other assertions of third-party intellectual property rights or claims arising from such
assertions will substantially harm our business and operating results. The defense of these claims and any future infringement claims, whether they are with or without merit or are determined in our favor, may result in costly litigation and
diversion of technical and management personnel. Furthermore, an adverse outcome of a dispute may require us to pay damages, potentially including treble damages and attorneys fees, if we are found to have willfully infringed a partys
patent or copyright rights; cease making, licensing or using products that are alleged to incorporate the intellectual property of others; expend additional development resources to redesign our products; and enter into potentially unfavorable
royalty or license agreements in order to obtain the right to use necessary technologies. Royalty or licensing agreements, if required, may be unavailable on terms acceptable to us, or at all. In any event, we may need to license intellectual
property which would require us to pay royalties or make one-time payments. Even if these matters do not result in litigation or are resolved in our favor or without significant cash settlements, the time and resources necessary to resolve them
could harm our business, operating results, financial condition, and reputation.

Valuation and other proprietary data may be
subject to disputes.

We provide data that is relevant to the decision to purchase a home and some of this data is
subject to revision, interpretation, or dispute. For example, our Trulia Estimate tool provides users with home valuations and is based on algorithms we have developed to analyze third-party data. We revise our algorithms regularly, which may
cause valuations to differ from those previously provided. Consumers and real estate professionals sometimes disagree with our estimates. Any such variation in or disagreements about the estimates that we present could result in negative user
feedback, harm our reputation, or lead to legal disputes.

We are subject to payments-related risks.

We accept payments using a variety of methods, including credit and debit cards. For certain payment methods, including credit and debit
cards, we pay bank interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We rely on third parties to provide payment processing services, including the processing of credit and debit cards
and our business would be disrupted if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements, and rules governing electronic funds
transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with

these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from consumers or facilitate other types of
online payments, and our business and operating results could be adversely affected.

Our business is subject to a variety of state and
federal laws, many of which are unsettled and still developing and which could subject us to claims or otherwise harm our business.

We are subject to a variety of federal and state laws, including laws regarding data retention, privacy, and consumer protection, that are continuously evolving and developing. The scope and
interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting. For example, laws relating to the liability of providers of online services for activities of their users and other third parties are
currently being tested by a number of claims, including actions based on invasion of privacy and other torts, unfair competition, copyright and trademark infringement, and other theories based on the nature and content of the materials searched, the
ads posted, or the content provided by users. In addition, regulatory authorities are considering a number of legislative and regulatory proposals concerning data protection and other matters that may be applicable to our business. Changes to
existing laws or regulations or the adoption of new laws or regulations could negatively affect our business. It is difficult to predict how existing laws will be applied to our business and the new laws to which we may become subject.

Our business may be adversely affected if we encounter difficulties as we implement an enterprise resource planning system.

We are in the process of implementing an enterprise resource planning, or ERP, systems for our company. This ERP system will combine and
streamline the management of our financial, accounting, human resources, sales and marketing and other functions, enabling us to more effectively manage operations and track performance. However, this ERP system will require us to complete numerous
processes and procedures for the effective use of this system or with running our business using this system, which may result in substantial costs. Until we have completed the implementation of an ERP system and have experience with its operation,
the implementation of the new ERP system poses a risk to our disclosure controls, internal control over financial reporting, and business operations. Any disruptions or difficulties in implementing this system could adversely affect our controls and
harm our business, including our ability to forecast or make sales and collect our receivables. Moreover, such disruption or difficulties could result in unanticipated costs or expenditures and diversion of managements attention and resources.

If we fail to remediate deficiencies in our internal control over financial reporting or are unable to implement and maintain effective
internal control over financial reporting in the future, the accuracy, and timeliness of our financial reporting may be adversely affected.

In connection with the audits of our financial statements for 2009, 2010, and 2011, we identified a material weakness in the design and operating effectiveness of our internal control over financial
reporting. A material weakness is a deficiency, or a combination of deficiencies, that creates a reasonable possibility that a material misstatement of a companys annual or interim financial statements will not be prevented or detected on a
timely basis.

The material weakness that we identified resulted from a lack of sufficient number of qualified personnel
within our accounting function that possessed an appropriate level of expertise to effectively perform the following functions:



identify, select, and apply GAAP sufficiently to provide reasonable assurance that transactions were being appropriately recorded; and



design control activities over the financial flows and reporting processes necessary to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements.

We are taking numerous steps that we believe will address the underlying causes of the
control deficiencies described above, primarily through the hiring of additional accounting and finance personnel with technical accounting and financial reporting experience, development and implementation of policies, and improved processes and
documented procedures. If we fail to effectively remediate deficiencies in our control environment or are unable to implement and maintain effective internal control over financial reporting to meet the demands that will be placed upon us as a
public company, including the requirements of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, we may be unable to accurately report our financial results, or report them within the timeframes required by law or exchange regulations.

Even if we are able to report our financial statements accurately and in a timely manner, if we do not make all necessary
improvements to address the material weakness, continued disclosure of a material weakness will be required in future filings with the Securities and Exchange Commission, or SEC, which could cause our reputation to be harmed and our stock price to
decline.

We have not performed an evaluation of our internal control over financial reporting, such as required by
Section 404 of the Sarbanes-Oxley Act, nor have we engaged our independent registered public accounting firm to perform an audit of our internal control over financial reporting as of any balance sheet date or for any period reported in our
financial statements. Had we performed such an evaluation or had our independent registered public accounting firm performed an audit of our internal control over financial reporting, control deficiencies, including material weaknesses and
significant deficiencies, in addition to those discussed above, may have been identified. In addition, we are an emerging growth company as defined in the Jumpstart Our Business Startups Act, and as such we may elect to avail ourselves
of the exemption from the requirement that our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act until we cease to be an emerging growth company.
See We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive
to investors, for additional risks relating to our emerging growth company status.

Complying with the laws and
regulations affecting public companies will increase our costs and the demands on management and could harm our operating results.

As a public company and particularly after we cease to be an emerging growth company, we will incur significant legal, accounting, and other expenses that we did not incur as a private
company. In addition, the Sarbanes-Oxley Act and rules subsequently implemented by the SEC and the New York Stock Exchange impose various requirements on public companies, including requiring changes in corporate governance practices. Our management
and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased and will continue to increase our legal, accounting, and financial compliance costs and have
made and will continue to make some activities more time-consuming and costly. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be
required to accept reduced policy limits and coverage or to incur substantial costs to maintain the same or similar coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified persons to serve on
our board of directors or our board committees or as executive officers.

In addition, the Sarbanes-Oxley Act requires, among
other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, beginning with the year ending December 31, 2013,
we will need to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm potentially to attest to, the effectiveness of
our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, or Section 404. As an emerging growth company we may elect to avail ourselves of the exemption from the requirement that our
independent registered public accounting firm attest to the effectiveness of our internal control over financial

reporting under Section 404 of the Sarbanes-Oxley Act. However, we may no longer avail ourselves of this exemption when we cease to be an emerging growth company and, when our
independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our compliance with applicable
provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting
requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over
financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial
and management resources.

Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this
could cause a decline in the market price of our stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our stated operating results and harm our
reputation. If we are unable to implement these changes effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in an adverse opinion on internal control from our independent registered
public accounting firm.

We are an emerging growth company, and any decision on our part to comply only with certain reduced
reporting and disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act enacted in April 2012, and, for as long as we continue to be an emerging growth company, we
may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies, including, but not limited to, not being required to have our independent
registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We could be an emerging growth company for up to five
years following the completion of this offering, although, if we have more than $1.0 billion in annual revenue, if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year, or
we issue more than $1.0 billion of non-convertible debt over a three-year period before the end of that five-year period, we would cease to be an emerging growth company as of the following December 31. We cannot predict if
investors will find our common stock less attractive if we choose to rely on these exemptions. If some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market
for our common stock and our stock price may be more volatile.

Under the Jumpstart Our Business Startups Act, emerging growth
companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and,
therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

We have pledged substantially all of our assets to secure indebtedness.

On September 15, 2011, we entered into a loan and security agreement with Hercules Technology Growth Capital, Inc., or Hercules,
providing for a secured term loan facility, or the credit facility, in an aggregate principal amount of up to $20.0 million to be used for general business purposes. Indebtedness we incur under this agreement is secured by substantially all of our
assets. This agreement contains customary affirmative and

negative covenants, including covenants that limit or restrict our ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends,
transfer assets, merge or consolidate, and make acquisitions. In May 2012, we failed to comply with the covenant that required delivery of audited financial statements for the year ended December 31, 2011 within the time period set forth in the
credit facility. Hercules granted a waiver arising from our failure to comply with this reporting covenant. If we default on our obligations under this agreement, Hercules may foreclose on our assets to repay our outstanding obligations to Hercules,
which would materially and adversely impact our business. As of June 30, 2012, we had drawn $10.0 million in term loans under the credit facility, and an additional $10.0 million in term loans remained available to be drawn, subject to the terms and
conditions of the credit facility. If we default on payments due pursuant to the credit facility and are forced to sell assets to satisfy these obligations, our business would be materially and adversely affected.

Our operating results may be harmed if we are required to collect sales taxes for our products.

There is general uncertainty in the industry about the obligation of Internet-based businesses to collect and remit sales taxes in
jurisdictions where their commerce is solely virtual. In the current climate, it is possible that one or more states or countries could seek to impose sales or other tax collection obligations on us or our subscribers with regards to our products,
which taxes may be applicable to past sales. A successful assertion that we should be collecting additional sales or other taxes on our products could result in substantial tax liabilities for past sales, discourage subscribers from purchasing our
products, or otherwise harm our business and operating results.

If we fail to expand effectively into adjacent markets, our growth
prospects could be harmed.

We intend to expand our operations into adjacent markets, such as rentals, mortgages, and
home improvement, and into international geographies. We may incur losses or otherwise fail to enter these markets successfully. Our expansion into these markets will place us in competitive environments with which we are unfamiliar and involves
various risks, including the need to invest significant resources and the possibility that returns on such investments will not be achieved for several years, or at all. In attempting to establish a presence in new markets, we expect to incur
significant expenses and face various other challenges, such as expanding our sales force and management personnel to cover these markets.

Future acquisitions and investments could disrupt our business and harm our financial condition and operating results.

Our success will depend, in part, on our ability to expand our products and markets, and grow our business in response to changing
technologies, user, and advertiser demands, and competitive pressures. In some circumstances, we may determine to do so through the acquisition of complementary businesses and technologies rather than through internal development, including, for
example, our recent acquisition of Movity, Inc., a geographic data company. The identification of suitable acquisition candidates can be difficult, time-consuming, and costly, and we may not be able to successfully complete identified acquisitions.
The risks we face in connection with acquisitions include:



diversion of management time and focus from operating our business to addressing acquisition integration challenges;



coordination of research and development and sales and marketing functions;



transition of the acquired companys users to our website and mobile applications;



retention of employees from the acquired company;



cultural challenges associated with integrating employees from the acquired company into our organization;

the need to implement or improve controls, procedures, and policies at a business that prior to the acquisition may have lacked effective controls,
procedures, and policies;



liability for activities of the acquired company before the acquisition, including patent and trademark infringement claims, violations of laws,
commercial disputes, tax liabilities, and other known and unknown liabilities; and



litigation or other claims in connection with the acquired company, including claims from terminated employees, users, former stockholders, or other
third parties.

Our failure to address these risks or other problems encountered in connection with our past
or future acquisitions and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to incur unanticipated liabilities, and harm our business generally. Future acquisitions could also
result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses, or the write-off of goodwill, any of which could harm our financial condition. Also, the anticipated benefits of any
acquisitions may not materialize.

We may require additional capital to support business growth, and this capital might not be available
on acceptable terms, if at all.

We intend to continue to make investments to support our business growth and may
require additional funds to respond to business challenges, including the need to develop new features and products or enhance our existing products, improve our operating infrastructure, or acquire complementary businesses and technologies.
Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution,
and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising
activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on
terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be
impaired, and our business may be harmed.

Risks Related to Ownership of Our Common Stock and this Offering

Concentration of ownership among our existing executive officers, directors, and their affiliates may prevent new investors from influencing
significant corporate decisions.

Upon completion of this offering, our executive officers, directors, and holders of
5% or more of our outstanding common stock will beneficially own, in the aggregate, approximately 61.1% of our outstanding shares of common stock. Some of these persons or entities may have interests that are different from yours. For example, these
stockholders may support proposals and actions with which you may disagree or which are not in your interests. These stockholders will be able to exercise a significant level of control over all matters requiring stockholder approval, including the
election of directors, amendment of our certificate of incorporation, and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of our company or changes in management and
will make the approval of certain transactions difficult or impossible without the support of these stockholders, which in turn could reduce the price of our common stock.

An active, liquid, and orderly trading market for our common stock may not develop, the price of our
stock may be volatile, and you could lose all or part of your investment.

Prior to this offering, there has been no
public market for shares of our common stock. The initial public offering price of our common stock will be determined through negotiation with the underwriters. This price will not necessarily reflect the price at which investors in the market will
be willing to buy and sell our shares of common stock following this offering. In addition, the trading price of our common stock following this offering is likely to be highly volatile and could be subject to wide fluctuations in response to
various factors, some of which are beyond our control.

In addition, the stock market in general, and the market for
technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect the
market price of companies stock, including ours, regardless of actual operating performance. These fluctuations may be even more pronounced in the trading market for our stock shortly following this offering. In addition, in the past,
following periods of volatility in the overall market and the market price of a particular companys securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us,
could result in substantial costs and a diversion of our managements attention and resources.

The price of our common stock may
be volatile, and you could lose all or part of your investment.

The trading price of our common stock following this
offering may fluctuate substantially and may be higher or lower than the initial public offering price. The trading price of our common stock following this offering will depend on a number of factors, including those described in this Risk
Factors section, many of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our common stock since you might be unable to sell your
shares at or above the price you paid in this offering. Factors that could cause fluctuations in the trading price of our common stock include the following:



price and volume fluctuations in the overall stock market from time to time;



volatility in the market prices and trading volumes of high technology stocks;



changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;



sales of shares of our common stock by us or our stockholders;



failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or our
failure to meet these estimates or the expectations of investors;



the financial projections we may provide to the public, any changes in those projections, or our failure to meet those projections;



announcements by us or our competitors of new products;



the publics reaction to our press releases, other public announcements, and filings with the SEC;



rumors and market speculation involving us or other companies in our industry;

conditions in the real estate industry or changes in mortgage interest rates; and



general economic conditions and slow or negative growth of our markets.

In addition, the stock market in general, and the market for technology companies in particular, have experienced extreme price and
volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may seriously affect the market price of our common stock, regardless of our actual operating
performance. In addition, in the past, following periods of volatility in the overall market and the market prices of a particular companies securities, securities class action litigations have often been instituted against these companies.
Litigation of this type, if instituted against us, could result in substantial costs and a diversion of our managements attention and resources.

A total of 20,376,654, or 77.3%, of our total outstanding shares after the offering are restricted from immediate resale, but may be sold on a stock exchange in the near future. The large number of
shares eligible for public sale or subject to rights requiring us to register them for public sale could depress the market price of our common stock.

The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the market after this offering, and the perception that these sales could occur
may also depress the market price of our common stock. Based on shares outstanding as of June 30, 2012, after giving effect to the issuance of 89,100 shares of our common stock to be acquired by certain stockholders through option exercises at the
closing of this offering in order to sell those shares in this offering, we will have 26,376,654 shares of common stock outstanding after this offering. Of these shares, the common stock sold in this offering will be freely tradable in the United
States, except for any shares purchased by our affiliates as defined in Rule 144 under the Securities Act of 1933. The holders of shares of outstanding common stock have agreed with the underwriters, subject to certain exceptions,
not to dispose of or hedge any of their common stock during the 180-day period beginning on the date of this prospectus, except with the prior written consent of J.P. Morgan Securities LLC and Deutsche Bank Securities Inc. After the expiration of
the 180-day restricted period, these shares may be sold in the public market in the United States, subject to prior registration in the United States, if required, or reliance upon an exemption from United States registration, including, in the case
of shares held by affiliates or control persons, compliance with the volume restrictions of Rule 144. In addition, a portion of these shares is subject to early release under certain circumstances described in the section titled
Underwriting in this prospectus.

Upon completion of this offering, stockholders owning an aggregate of 20,376,654
shares will be entitled, under contracts providing for registration rights, to require us to register shares of our common stock owned by them for public sale in the United States. In addition, we intend to file a registration statement to register
the approximately 6,112,904 shares reserved for future issuance under our equity compensation plans. Upon effectiveness of that registration statement, subject to the satisfaction of applicable exercise periods and, in certain cases, lock-up
agreements with the representatives of the underwriters referred to above, the shares of common stock issued upon exercise of outstanding options will be available for immediate resale in the United States in the open market.

Sales of our common stock as restrictions end or pursuant to registration rights may make it more difficult for us to sell equity
securities in the future at a time and at a price that we deem appropriate. These sales also could cause our stock price to fall and make it more difficult for you to sell shares of our common stock.

Anti-takeover provisions contained in our certificate of incorporation and bylaws, as well as
provisions of Delaware law, could impair a takeover attempt.

Our certificate of incorporation, bylaws, and Delaware
law contain or will contain provisions which could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our board of directors. Our corporate governance documents include or will include
provisions:

authorizing blank check preferred stock, which could be issued by our board of directors without stockholder approval and may contain
voting, liquidation, dividend, and other rights superior to our common stock;

limiting the ability of our stockholders to call and bring business before special meetings;



requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for
election to our board of directors;



controlling the procedures for the conduct and scheduling of board of directors and stockholder meetings; and



providing our board of directors with the express power to postpone previously scheduled annual meetings and to cancel previously scheduled special
meetings.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in
control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including
Section 203 of the Delaware General Corporation law, which prevents some stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations without approval of the holders of substantially all of
our outstanding common stock.

Any provision of our certificate of incorporation, bylaws or Delaware law that has the effect
of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.

We may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a return.

The net proceeds from the sale of our shares of common stock by us in this offering may be used for general corporate
purposes, including working capital. We may also use a portion of the net proceeds to acquire complementary businesses, products, services, or technologies. However, we do not have any agreements or commitments for any acquisitions at this time. Our
management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be
invested with a view towards long-term benefits for our stockholders and this may not increase our operating results or market value. Until the net proceeds are used, they may be placed in investments that do not produce significant income or that
may lose value.

Purchasers in this offering will experience immediate and substantial dilution in the book value of their investment.

The anticipated initial public offering price of our common stock of $15.00, which is the midpoint of the estimated
offering price range set forth on the cover page of this prospectus, is substantially higher than the net tangible book value per share of our outstanding common stock immediately after this offering. Therefore, if you

purchase our common stock in this offering, you will incur immediate dilution of $12.68 in the net tangible book value per share from the price you paid. In addition, following this offering,
purchasers in the offering will have contributed 64.7% of the total consideration paid by our stockholders to purchase shares of common stock, in exchange for acquiring approximately 19.0% of our total outstanding shares as of June 30, 2012 after
giving effect to this offering. The exercise of outstanding stock options will result in further dilution.

If securities or industry
analysts do not publish or cease publishing research or reports about us, our business or our market, or if they change their recommendations regarding our stock adversely, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts may publish
about us, our business, our market, or our competitors. If any of the analysts who may cover us change their recommendation regarding our stock adversely, or provide more favorable relative recommendations about our competitors, our stock price
would likely decline. If any analyst who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to
decline.

We do not expect to declare any dividends in the foreseeable future.

We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. In addition, the terms of our
credit facility currently prohibit us from paying cash dividends on our capital stock. Consequently, investors may need to rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future
gains on their investment. Investors seeking cash dividends should not purchase our common stock.

This prospectus contains forward-looking statements within the meaning of the federal securities laws, which statements
involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as
may, will, should, expects, plans, anticipates, could, intends, target, projects, contemplates, believes,
estimates, predicts, potential or continue or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements
contained in this prospectus include, but are not limited to, statements about:

the continued availability of home listing and other information relevant to the real estate industry;



the growth in the usage of our mobile applications and our ability to successfully monetize this usage;



our ability to innovate and provide a superior user experience;



our ability to capitalize on adjacent opportunities;



the effects of the market for real estate and general economic conditions on our business; and



the attraction and retention of qualified employees and key personnel.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this prospectus.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements
contained in this prospectus primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, and prospects. The outcome of the events described
in these forward-looking statements is subject to risks, uncertainties, and other factors described in the section titled Risk Factors and elsewhere in this prospectus. Moreover, we operate in a very competitive and rapidly changing
environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this prospectus. We cannot assure you
that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made.
We undertake no obligation to update any forward-looking statements made in this prospectus to reflect events or circumstances after the date of this prospectus or to reflect new information or the occurrence of unanticipated events, except as
required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect
the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

This prospectus also contains statistical data, estimates, and forecasts that are based on
independent industry publications, such as those published by Borrell Associates, the National Association of Realtors, and the Real Estate Book, or other publicly available information, as well as other information based on our internal sources.
Although we believe that the third-party sources referred to in this prospectus are reliable, neither we nor the underwriters have independently verified the information provided by these third parties. While we are not aware of any misstatements
regarding any third-party information presented in this prospectus, their estimates, in particular, as they relate to projections, involve numerous assumptions, are subject to risks and uncertainties, and are subject to change based on various
factors, including those discussed under the section titled Risk Factors and elsewhere in this prospectus.

We estimate that the net proceeds from the sale of shares of our common stock that we are selling in this offering will be approximately
$65.8 million, based upon an assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts
and commissions and estimated offering expenses payable by us. If the underwriters option to purchase additional shares from us is exercised in full, we estimate that our net proceeds would be approximately $78.3 million, after deducting
estimated underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any proceeds from the sale of shares of our common stock by the selling stockholders.

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share would increase or decrease the net
proceeds that we receive from this offering by approximately $4.7 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts
and commissions payable by us. Similarly, each increase or decrease of one million in the number of shares of common stock offered by us would increase or decrease the net proceeds that we receive from this offering by approximately $14.0 million,
assuming the assumed initial public offering price remains the same and after deducting the estimated underwriting discounts and commissions payable by us.

The principal purposes of this offering are to increase our financial flexibility, create a public market for our common stock, and facilitate our future access to the public equity markets.

We currently intend to use the net proceeds that we will receive from this offering for working capital and other general corporate
purposes. We may also use a portion of the net proceeds that we receive to acquire or invest in complementary businesses, products, services, technologies, or other assets. We have not entered into any agreements or commitments with respect to any
acquisitions or investments at this time.

We cannot specify with certainty the particular uses of the net proceeds that we
will receive from this offering. Accordingly, we will have broad discretion in using these proceeds. Pending the use of proceeds from this offering as described above, we plan to invest the net proceeds that we receive in this offering in short-term
and intermediate-term interest-bearing obligations, investment-grade investments, certificates of deposit, or direct or guaranteed obligations of the U.S. government.

We have never declared or paid any cash dividend on our capital stock. We currently intend to retain any future earnings and do not
expect to pay any dividends in the foreseeable future. Any future determination to declare cash dividends will be made at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors, including our
financial condition, results of operations, capital requirements, contractual restrictions, general business conditions, and other factors that our board of directors may deem relevant. In addition, the terms of our credit facility currently
prohibit us from paying cash dividends on our capital stock.

The following table sets forth cash and cash equivalents and short-term investments, as well as our capitalization, as of June 30, 2012
as follows:



on an actual basis;



on a pro forma basis, giving effect to the automatic conversion of all outstanding shares of our convertible preferred stock into an aggregate of
14,161,444 shares of common stock, which conversion will occur immediately prior to the completion of this offering, as if such conversion had occurred on June 30, 2012, and the resulting reclassification of the preferred stock warrant liability to
additional paid-in capital; and



on a pro forma as adjusted basis, giving effect to (i) the pro forma adjustments set forth above, (ii) the sale and issuance by us of 5,000,000 shares
of common stock in this offering, based on an assumed initial public offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable by us, (iii) option exercises at the closing of this offering by certain selling stockholders in order to sell those shares in this offering, and (iv) the filing and
effectiveness of our amended and restated certificate of incorporation in Delaware immediately prior to the completion of this offering.

The pro forma as adjusted information set forth in the table below is illustrative only and will be adjusted based on the actual initial public offering price and other final terms of this offering. You
should read this table together with our financial statements and related notes, and the sections titled Selected Financial and Other Data and Managements Discussion and Analysis of Financial Condition and Results of
Operations that are included elsewhere in this prospectus.

If the underwriters option to purchase additional shares from us were exercised in
full, pro forma as adjusted cash and cash equivalents and short-term investments, additional paid-in capital, total stockholders equity (deficit) and shares outstanding as of June 30, 2012 would be $88.9 million, $119.8 million,
$75.9 million and 27,276,654, respectively.

Each $1.00 increase or decrease in the assumed initial public offering
price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, our cash and cash equivalents and short-term investments, additional
paid-in capital, and total stockholders equity (deficit) by approximately $4.7 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated
underwriting discounts and commissions payable by us.

The pro forma and pro forma as adjusted columns in the table above
exclude the following:



3,340,370 shares of common stock issuable upon the exercise of options to purchase common stock that were outstanding as of June 30, 2012 (which does
not include 89,100 shares to be sold in this offering by certain selling stockholders upon the exercise of options), with a weighted average exercise price of $4.39 per share;



402,534 shares of common stock issuable upon the exercise of options to purchase common stock granted after June 30, 2012, with a weighted average
exercise price of $16.53 per share;



44,646 shares of common stock issuable upon the exercise of a warrant to purchase common stock that was outstanding as of June 30, 2012, with an
exercise price of $4.29 per share;



Up to 120,961 shares of common stock, on an as-converted basis, issuable upon the exercise of a warrant to purchase convertible preferred stock that
was outstanding as of June 30, 2012, with an exercise price of $8.47 per share, of which 56,054 were exercisable as of June 30, 2012; and



2,370,000 shares of common stock reserved for future issuance under our 2012 Equity Incentive Plan, which will become effective prior to the completion
of this offering, and which contains provisions that automatically increase its share reserve each year.

If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the difference between the
initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering. Net tangible book value dilution per share to new investors represents
the difference between the amount per share paid by purchasers of shares of common stock in this offering and the pro forma as adjusted net tangible book value per share of common stock immediately after completion of this offering.

Net tangible book value per share is determined by dividing our total tangible assets less our total liabilities by the number of shares
of common stock outstanding. Our historical net tangible book value (deficit) as of June 30, 2012 was $(5.4) million, or $(0.76) per share. Our pro forma net tangible book value (deficit) as of June 30, 2012 was $(4.8) million, or $(0.22)
per share, based on the total number of shares of our common stock outstanding as of June 30, 2012, after giving effect to the automatic conversion of all outstanding shares of our convertible preferred stock as of June 30, 2012 into an aggregate of
14,161,444 shares of common stock, which conversion will occur immediately prior to the completion of this offering, and the resulting reclassification of the preferred stock warrant liability to additional paid-in capital.

After giving effect to the sale by us of 5,000,000 shares of common stock in this offering at the assumed initial public offering price
of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, as
well as the issuance of 89,100 shares of our common stock to be acquired by certain selling stockholders through option exercises at the closing of this offering in order to sell those shares in this offering, our pro forma as adjusted net tangible
book value as of June 30, 2012 would have been $61.2 million, or $2.32 per share. This represents an immediate increase in pro forma net tangible book value of $2.54 per share to our existing stockholders and an immediate dilution in pro forma net
tangible book value of $12.68 per share to investors purchasing shares of common stock in this offering at the assumed initial public offering price. The following table illustrates this dilution:

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share, which
is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, our pro forma as adjusted net tangible book value per share to new investors by $0.18, and would
increase or decrease, as applicable, dilution per share to new investors in this offering by $0.82, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated
underwriting discounts and commissions payable by us. In addition, to the extent any outstanding options or warrants to purchase common stock or convertible preferred stock are exercised, new investors would experience further dilution. If the
underwriters exercise their option to purchase additional shares from us in full, the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering would be $2.71 per share, and the dilution in pro forma
net tangible book value per share to new investors in this offering would be $12.29 per share.

The following table presents,
on a pro forma as adjusted basis as of June 30, 2012, after giving effect to the conversion of all outstanding shares of convertible preferred stock into common stock immediately prior to the completion of this offering, the differences between the
existing stockholders and the new investors purchasing shares of our common stock in this offering with respect to the number of shares purchased from us, the total

consideration paid or to be paid to us, which includes net proceeds received from the issuance of common stock and convertible preferred stock, cash received from the exercise of stock options,
and the average price per share paid or to be paid to us at an assumed offering price of $15.00 per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, before deducting estimated
underwriting discounts and commissions and estimated offering expenses payable by us:

Each $1.00 increase or decrease in the assumed initial public offering price of $15.00 per share, which
is the midpoint of the estimated offering price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, the total consideration paid by new investors and total consideration paid by all stockholders by
approximately $4.7 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions payable by us. In addition, to the
extent any outstanding options or warrants to purchase common stock or convertible preferred stock are exercised, new investors will experience further dilution.

Except as otherwise indicated, the above discussion and tables assume no exercise of the underwriters option to purchase additional shares. If the underwriters exercise their option to purchase
additional shares in full from us, our existing stockholders would own 78.4% and our new investors would own 21.6% of the total number of shares of our common stock outstanding upon the completion of this offering.

The number of shares of our common stock to be outstanding after this offering is based on the number of shares of our common stock
outstanding as of June 30, 2012, and after giving effect to the issuance of 89,100 shares of our common stock to be acquired by certain selling stockholders through option exercises at the closing of this offering in order to sell those shares in
this offering, and excludes:



3,340,370 shares of common stock issuable upon the exercise of options to purchase common stock that were outstanding as of June 30, 2012 (which does
not include 89,100 shares to be sold in this offering by certain selling stockholders upon the exercise of options), with a weighted average exercise price of $4.39 per share;



402,534 shares of common stock issuable upon the exercise of options to purchase common stock granted after June 30, 2012, with a weighted average
exercise price of $16.53 per share;



44,646 shares of common stock issuable upon the exercise of a warrant to purchase common stock that was outstanding as of June 30, 2012, with an
exercise price of $4.29 per share;



Up to 120,961 shares of common stock, on an as-converted basis, issuable upon the exercise of a warrant to purchase convertible preferred stock that
was outstanding as of June 30, 2012, with an exercise price of $8.47 per share, of which 56,054 were exercisable as of June 30, 2012; and



2,370,000 shares of common stock reserved for future issuance under our 2012 Equity Incentive Plan, which will become effective prior to the completion
of this offering, and which contains provisions that automatically increase its share reserve each year.

Non-GAAP Financial Measures

Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles in the United States, or GAAP. We define Adjusted EBITDA as net loss adjusted to
exclude interest income, interest expense, depreciation and amortization, change in the fair value of our warrant liability and stock-based compensation. Below, we have provided a reconciliation of Adjusted EBITDA to our net loss, the most directly
comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of financial performance calculated and presented in accordance with GAAP. Our
Adjusted EBITDA may not be comparable to similarly titled measures of other organizations because other organizations may not calculate Adjusted EBITDA in the same manner as we calculate the measure.

We include Adjusted EBITDA in this prospectus because it is an important measure upon which our management assesses our operating
performance. We use Adjusted EBITDA as a key performance measure because we believe it facilitates operating performance comparisons from period to period by excluding potential differences primarily caused by variations in capital structures, tax
positions, the impact of depreciation and amortization expense on our fixed assets, changes related to the fair value remeasurements of our preferred stock warrant, and the impact of stock-based compensation expense. Because Adjusted EBITDA
facilitates internal comparisons of our historical operating performance on a more consistent basis, we also use Adjusted EBITDA for business planning purposes, to incentivize and compensate our management personnel, and in evaluating acquisition
opportunities. In addition, we believe Adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and
debt-service capabilities.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not
consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:



Adjusted EBITDA does not reflect our cash expenditures for capital equipment or other contractual commitments;



Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and
Adjusted EBITDA does not reflect capital expenditure requirements for such replacements;

Adjusted EBITDA does not reflect the interest expense or the cash requirements necessary to service interest or principal payments on our
indebtedness; and



Other companies, including companies in our industry, may calculate Adjusted EBITDA measures differently, which reduces their usefulness as a
comparative measure.

In evaluating Adjusted EBITDA, you should be aware that in the future we will incur
expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating
our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

The following table presents a reconciliation of Adjusted EBITDA to our net loss, the most comparable GAAP measure, for each of the periods indicated:

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations
should be read in conjunction with the section titled Selected Financial and Other Data and financial statements and related notes thereto included elsewhere in this prospectus. This discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the
section titled Risk Factors included elsewhere in this prospectus.

Overview

Trulia is redefining the home search experience for consumers and changing the way that real estate professionals build their businesses.
Our marketplace, delivered through the web and mobile applications, gives consumers powerful tools to research homes and neighborhoods and enables real estate professionals to efficiently market their listings and attract new clients. We believe we
deliver the best home search experience by combining our superior user interface with our comprehensive database of real estate properties, local insights, and user-generated content. We offer products that provide real estate professionals with
access to transaction-ready consumers and help them enhance their online presence.

Key elements of our marketplace are
extensive consumer reach, an engaged base of real estate professionals and a comprehensive database of real estate information and local insights. In the six months ended June 30, 2012, we had 22.0 million monthly unique visitors, and as of June 30,
2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers. Our large, continually refreshed, and searchable database contains more than 110 million properties, including 4.5
million homes for sale and rent. We supplement listings data with local information on schools, crime and neighborhood amenities to provide unique insights into each community. In addition, we harness rich, insightful user-generated content from our
active community of contributors, including consumers, local enthusiasts, and real estate professionals. With more than 5 million unique user contributions, we believe we have the largest collection of user-generated content on homes, neighborhoods,
and real estate professionals. We deliver this information on mobile devices through our iPhone, iPad, Android, and Kindle applications and also provide tailored mobile experiences, such as GPS-based search.

We offer our products free to consumers. We deliver the inside scoop on homes, neighborhoods, and real estate professionals
in an intuitive and engaging way, helping consumers make more informed housing decisions. For real estate professionals, we offer a suite of free and subscription products to promote themselves and their listings online, and to connect with
consumers searching for homes. Our free products attract users to our marketplace and the quality of our products drives the growth of our audience and promotes deep engagement by our users. We believe this leads real estate professionals to convert
to paying subscribers and brand advertisers to purchase our advertising products.

We generate revenue primarily from sales of
subscription marketing products that we offer to real estate professionals. Our Trulia Pro product allows real estate professionals to receive prominent placement of their listings in our search results. With our Trulia Local Ads and
Trulia Mobile Ads products, real estate professionals can purchase local advertising on our website and mobile applications, respectively, by locale and by share of a given market. We also generate revenue from display advertising we sell to
leading real estate advertisers and consumer brands seeking to reach our attractive audience. Pricing for our display advertisements is based on advertisement size and position on our web page, and fees are based on a per-impression or on a
per-click basis.

To date, we have focused our efforts and investments on developing and delivering superior products and user
experiences, attracting consumers and real estate professionals to our marketplace, and growing our revenue. We have invested heavily to build our robust data and analytics platform, and continue to spend significantly on

technology and engineering. In 2005, we launched the initial version of our website. Since then, we have become one of the leading online real estate marketplaces in the United States by
achieving key product development and business milestones that have driven our revenue and user growth, including:



In May 2007, we launched Trulia Voices, a forum for our users to get the inside scoop on what it is like to live in a neighborhood
from our community of contributors, including consumers, local enthusiasts, and real estate professionals;



In June 2008, we launched Trulia Pro, a premium advertising product by which real estate professionals promote their listings and market
themselves to consumers;



In August 2008, we launched our first mobile product for consumers with a home search application on the iPhone and our mobile-optimized website
m.trulia.com for consumers that is available on any mobile device browser;

In December 2010, we acquired Movity, Inc., a geographic data company, for its engineering team and its data visualization expertise;



In January 2011, we expanded our presence by opening a dedicated sales and customer service center in Denver, Colorado, increasing our headcount by 149
people;



In March 2011, we expanded our mobile products for consumers with home search applications on the iPad and Android phones;



In December 2011, we launched Trulia for Agents on the iPhone, a mobile application dedicated to helping real estate professionals. Key features
of the application include check-ins and lead notifications; and



In May 2012, we launched Trulia Mobile Ads, an innovative marketing product that allows real estate professionals to target consumers who are
researching homes on mobile devices.

We have experienced rapid growth in the past three years. In the years
ended December 31, 2009, 2010, and 2011, and the six months ended June 30, 2012, we generated revenue of $10.3 million, $19.8 million, $38.5 million, and $29.0 million, respectively. During the same period, we had net losses of $7.0
million, $3.8 million, $6.2 million, and $7.6 million, respectively.

Opportunities and Challenges

We believe that the growth of our business and our future success are dependent upon many factors including our ability to increase our
audience size and user engagement, grow the number of subscribers in our marketplace, increase the value of our advertising products, and successfully invest in our growth. While each of these areas presents significant opportunities for us, they
also pose important challenges that we must successfully address in order to sustain the growth of our business and improve our operating results.

Increase in Audience Size and User Engagement. We believe that increases in audience size and user engagement would make our marketplace more attractive to real estate professionals and advertisers
which could lead to additional subscriptions, higher rates for our subscription products, more display advertising, and higher rates for display advertising. In order to increase our audience size and user engagement, we plan to continuously enhance
and refresh our database of homes, to partner with third parties to add new and relevant local content, and to develop new features, tools, and products, each of which may increase our expenses. If we are not able to increase audience size and user
engagement in our marketplace, we may not be able to increase the revenue from our subscription and display advertising products, and our operating results may be harmed.

Growth in the Number of Subscribers in our Marketplace. We believe that we will need to further penetrate the large base of more than 2.8 million real estate professionals in the United States in
order to increase our

revenues and improve our operating results. As of June 30, 2012, we had more than 360,000 active real estate professionals in our marketplace, 21,544 of whom were paying subscribers. If we are
able to increase the number of paying subscribers in our marketplace, we expect that this would increase our revenue and improve our operating results, and any failure to increase the number of paying subscribers in our marketplace would adversely
affect our revenue and operating results. To attract additional real estate professionals to our marketplace and to encourage real estate professionals to become paying subscribers, we plan to communicate the value of our free and subscription
products, to continue to offer our subscribers high-quality leads from consumers using our marketplace, to enhance and increase the ways that real estate professionals can market themselves and communicate with prospective clients in our
marketplace, and to create additional value-added products to help professionals more effectively manage their leads, documents, and other key elements of their business. We expect that our expenses will increase as we take these actions to increase
the number of real estate professionals and subscribers in our marketplace. In addition, our sales and marketing expenses were our largest operating expenses in 2011 and the six months ended June 30, 2012. Sales and marketing expenses reflect many
of the costs that we incur in acquiring new subscribers and retaining existing subscribers, and we expect that sales and marketing expenses will continue to increase in absolute dollars as we seek to grow the number of subscribers in our
marketplace.

Increase Value of Advertising Products. We intend to continue to increase the attractiveness of our
display advertising products in order to increase advertiser demand and thereby increase the amount advertisers spend with us. We aim to increase the attractiveness of our advertising products through increasing the size of our audience and
engagement of our users, improving our ability to select relevant content of interest to individual users, and improving the measurement tools available to advertisers to optimize their campaigns.

Investments for Growth. We expect to continue to invest in our marketplace, our infrastructure, and our personnel in order to
drive future growth, as well as to pursue adjacent opportunities. We plan to continuously enhance and refresh our database of homes and make ongoing product enhancements intended to improve the user experience. We also expect to continue to make
investments in our technical infrastructure to ensure that our growing user base can access our marketplace rapidly and reliably. In addition, we anticipate continuing to increase our headcount to ensure that our research and development function
drives improvements in our marketplace and our sales and marketing function maximizes opportunities for growing our business and revenue. As part of our strategy, we also intend to invest in pursuing opportunities in large adjacent markets, such as
rentals, mortgages, home improvement, and agent tools, and to expand our business internationally. We expect that these investments will increase our operating expenses, and that any increase in revenue resulting from these investments will likely
trail the increase in expenses.

Key Business Metrics

To analyze our business performance, determine financial forecasts, and help develop long-term strategic plans, we review the following key business metrics:



Monthly Unique Visitors. We count a unique visitor the first time a computer or mobile device with a unique IP address accesses our website or
our mobile applications during a calendar month. If an individual accesses our website or mobile applications using different IP addresses within a given month, the first access by each such IP address is counted as a separate unique visitor. Our
number of monthly unique visitors includes mobile monthly unique visitors. We calculate our monthly unique visitors based on the monthly average over the applicable period. We view monthly unique visitors as a key indicator of the growth in our
business and audience reach, the quality of our products, and the strength of our brand awareness. In the six months ended June 30, 2012, the number of monthly unique visitors increased to 22.0 million from 13.4 million in the six months ended
June 30, 2011, a 64% increase. We attribute the growth in our monthly unique visitors principally to our increasing brand awareness, the popularity of our mobile products and the overall industry trend of more consumers using the web and mobile
applications to research housing decisions.

Mobile Monthly Unique Visitors. We count a unique mobile visitor the first time a mobile device with a unique IP address accesses our website or
our mobile applications during a calendar month. We calculate our mobile monthly unique visitors based on the monthly average over the applicable period. These mobile monthly unique visitors are included in the monthly unique visitors metric. We
view mobile monthly unique visitors as a key indicator of the growth in our business and audience reach, and believe that having more unique visitors using our mobile applications will drive faster growth in our revenue. We plan to expand our mobile
products to support our rapidly growing mobile user base. In the six months ended June 30, 2012, the number of mobile monthly unique visitors increased to 4.4 million from 1.6 million in the six months ended June 30, 2011, a 176% increase. We
attribute this growth to the overall adoption of smartphones and the growth of mobile applications and mobile web use by consumers. We also attribute the growth in our mobile monthly unique visitors to our increased efforts in developing a mobile
website and mobile applications. Due to the significant growth rate of usage of our mobile products and solutions, our mobile monthly unique visitors has grown as a percentage of our monthly unique visitors over recent periods and we expect this
trend to continue.



New Contributions to User-Generated Content. We define user-generated content as any content contributed by a user through our website or mobile
applications, such as Q&A discussions, blogs, blog comments, user votes, recommendations, and neighborhood ratings and reviews. We view the changes in the volume of new contributions to user-generated content as a key indicator of our user
engagement and the strength of our community. In the six months ended June 30, 2012, new contributions to user-generated content increased by 1,397,200 contributions, and we now have over 5 million cumulative contributions on our marketplace. We
expect new contributions to user-generated content to continue to grow as our monthly unique visitors and total subscribers grow and as we introduce new features to our marketplace. While the absolute number of new contributions to user-generated
content may continue to grow period-over-period, the rate of growth has slowed and we expect that the rate of growth may continue to slow as the aggregate size of our user-generated content increases. We believe the slowing growth rate of new
contributions to user-generated content is a function of the large historical number of new contributions to user-generated content on our marketplace, which makes achievement of increasing rates of growth more challenging. We continue to focus on
promoting new contributions to user-generated content to increase the engagement of our users with our marketplace.



Total Subscribers. We define a subscriber as a real estate professional with a paid subscription at the end of a period. Total subscribers has
been, and we expect will continue to be, a key driver of revenue growth. It is also an indicator of our market penetration, the value of our products, and the attractiveness of our consumer audience to real estate professionals. As of June 30, 2012,
we had 21,544 total subscribers, a 46% increase from 14,766 total subscribers as of June 30, 2011. We attribute this growth to our increasing sales and marketing efforts, principally from the launch and growth of our inside sales team, as well as
growth in monthly unique visitors. Although our total subscribers are growing period-over-period and we expect total subscribers to continue to grow, the rate of growth may slow as we increase efforts to sell more products to existing subscribers.
In addition, subscribers often purchase subscriptions for limited periods as a result of seasonality, as part of their advertising campaigns, and other factors.



Average Monthly Revenue per Subscriber. We calculate our average monthly revenue per subscriber by dividing the revenue generated from
subscriptions in a period by the average number of subscribers in the period, divided again by the number of months in the period. Our average number of subscribers is calculated by taking the average of the beginning and ending number of
subscribers for the period. Our average monthly revenue per subscriber is a key indicator of our ability to monetize our marketplace, and we monitor changes in this metric to measure the effectiveness of our marketplace monetization strategy. In the
six months ended June 30, 2012, our average monthly revenue per subscriber increased to $140 from $91 in the six months ended June 30, 2011, a 54% increase. We have been able to increase our average monthly revenue per subscriber by launching new
products to sell to existing customers, raising prices in certain geographic markets, and selling to existing subscribers the

additional advertising inventory created by traffic growth to our marketplace. In addition, in geographic markets that show strong demand for our subscription productsthose where inventory
is sold out and wait lists to purchase our products existaverage monthly revenue per subscriber is higher than in markets with less demand for our products. While the average monthly revenue per subscriber has increased and may continue to
increase in absolute dollars period-over-period, the rate of increase has slowed and we expect that the rate of increase may continue to slow as the average monthly revenue per subscriber increases. We believe that the slowing growth rate of our
average monthly revenue per subscriber is the result of our larger subscriber base and the resulting challenge associated with achieving higher growth rates. Despite this slowing growth rate, we believe we have significant opportunities to continue
to increase average monthly revenue per subscriber by further penetrating markets and by offering new products to existing subscribers.

Components of Statements of Operations

Revenue

Our revenue is comprised of marketplace revenue and media revenue.

Marketplace Revenue. Marketplace revenue primarily consists of our fixed-fee subscription products. We currently provide two sets
of products to real estate professionals on a subscription basis. The first set of products, which include Trulia Local Ads and Trulia Mobile Ads, enables real estate professionals to promote themselves on our search results pages and
property details pages for a local market area. Real estate professionals purchase subscriptions to this product based upon their specified market share for a city or zip code, at a fixed monthly price, for periods ranging from one month to one
year, with pricing depending on the location and the percentage of market share purchased. We price Trulia Local Ads and Trulia Mobile Ads subscriptions similarly based on geography, the share of a market, and demand. Our second set of
products allows real estate professionals to receive prominent placement of their listings in our search results. Real estate professionals sign up for subscriptions to this service at a fixed monthly price for periods that generally range from
one month to 12 months. We recognize our subscription revenue ratably over the term of the subscription.

Media Revenue.
We derive media revenue from sales of display advertisements to real estate advertisers, such as home improvement companies and mortgage lenders. We also derive media revenue from sales of display advertisements to leading consumer brands, such
as home furnishings, cable, and automotive companies. Our media products enable our customers to display advertisements to promote their brand on our website and mobile website, m.trulia.com. Pricing is based on advertisement size and position on
our web page, and fees are billed monthly, based on a per impressions or a per click basis. Impressions are the number of times an advertisement is loaded on our web page, and prices are measured on a cost per thousand, or CPM, basis. Clicks are the
number of times users click on an advertisement, and prices are measured on a cost per click, or CPC, basis. CPC is based on the number of times a user clicks an advertisement. This media revenue is recognized in the periods the clicks or
impressions are delivered. Our media revenue is generated primarily through advertisements placed on our website, although we do generate some media revenue from display advertising on our mobile website. We price display advertisements on our
mobile website on a per-impression basis. We also ran one display advertising campaign for an advertiser in November and December 2011 on our iPad mobile application, and we may offer display advertising on our other mobile applications in the
future. We do not

currently generate any media revenue from our mobile applications. As our mobile web pages offer less space on which to display advertising, a shift in user traffic from our website to mobile
products could decrease our advertising inventory and negatively affect our media revenue. We do not believe that we have experienced a shift in user traffic from our website to our mobile applications, as our monthly unique visitors and mobile
monthly unique visitors each continued to grow at a rapid pace.

During the years ended December 31, 2009, 2010, and 2011
and the six months ended June 30, 2011 and 2012, we recognized marketplace revenue and media revenue as follows:

For the years ended December 31, 2009 and 2010, because we had not yet established the fair value for each element, revenue for multiple element
arrangements was recognized ratably over the contract term for financial reporting purposes. However, in order to provide added transparency and help facilitate the discussion herein, we have separated marketplace and media revenue based on selling
prices, which management has determined to be a reasonable separation methodology.

Both our marketplace
revenue and media revenue have grown over the periods disclosed above. Our marketplace revenue has grown significantly faster than our media revenue and, as a result, now constitutes the majority of our total revenue. We expect this trend to
continue and for the percentage of our media revenue, as a share of our total revenue, to continue to decline.

Technology and Development. Technology and
development expenses consist primarily of headcount related expenses including salaries, bonuses, benefits and stock-based compensation expense, third-party contractor fees, and allocated overhead primarily associated with developing new
technologies. Technology and development also includes amortization expenses related to capitalized costs from internal and external development activities for our marketplace.

Sales and Marketing. Sales and marketing expenses consist primarily of headcount-related expenses including salaries, bonuses,
commissions, benefits and stock-based compensation expense for sales, customer service, marketing, and public relations employees and third-party contractor fees. Sales and marketing expenses also include other sales expenses related to promotional
and marketing activities, and allocated overhead.

General and Administrative. General and administrative expenses
consist primarily of headcount related expenses including salaries, bonuses, and benefits and stock-based compensation expense for executive, finance, accounting, legal, human resources, recruiting, and administrative support personnel. General and
administrative expenses also include legal, accounting, and other third-party professional service fees, bad debt, and allocated overhead.

Interest expense consists primarily of interest on our outstanding long-term debt and capital lease obligations. See Note 6 of our audited
financial statements included elsewhere in this prospectus for more information about our long-term debt and Note 7 for more information about our capital lease obligations.

Change in Fair Value of Warrant Liability

Change in the fair value of the
warrant liability includes charges from the remeasurement of our preferred stock warrant liability on a mark-to-market basis as of each period end. These preferred stock warrants will remain outstanding until the earlier of the exercise or
expiration of the warrants or the completion of our initial public offering, at which time, the warrant liability will be remeasured to fair value and any remaining liability will be reclassified to additional paid-in capital. See Note 9 of the
audited financial statements included elsewhere in this prospectus for more information about our preferred stock warrants.

Provision for Income Taxes

Our provision for income taxes has not been historically significant to our business as we have incurred losses to date. We currently have federal and state net operating loss carryforwards of $29.7
million and $24.9 million, which expire at various dates beginning in 2025 and 2015, respectively. See Note 12 of our audited financial statements included elsewhere in this prospectus for more information about our provision for income taxes.

The Internal Revenue Code provides limitations on our ability to utilize net operating loss carryforwards and certain other
tax attributes, including tax credit carryforwards, after an ownership change, as defined in Section 382 of the Internal Revenue Code. California has similar rules that may limit our ability to utilize our state net operating loss
carryforwards. If we were to experience an ownership change in the future, this could limit our use of our net operating loss carryforwards.

Revenue increased to $29.0 million in the six months ended June 30, 2012 from $16.2 million in the
six months ended June 30, 2011, an increase of $12.8 million, or 78%. Marketplace revenue and media revenue represented 68% and 32%, respectively, of total revenue in the six months ended June 30, 2012, compared to 54% and 46%, respectively, of
total revenue in the six months ended June 30, 2011. The continued increase in marketplace revenue as a percentage of total revenue was the result of significant growth in our subscription business. Increases in total subscribers and average monthly
revenue per subscriber outpaced the growth of our advertising business.

Marketplace revenue increased to $19.7 million in the six months ended June 30, 2012 from
$8.7 million in the six months ended June 30, 2011, an increase of $11.0 million, or 126%. The increase in marketplace revenue was primarily attributable to the 54% increase in the average monthly revenue per subscriber from $91 in the six
months ended June 30, 2011 to $140 in the six months ended June 30, 2012, which resulted in a $5.7 million increase in marketplace revenue during the six months ended June 30, 2012 when compared to the six months ended June 30, 2011. The increase in
marketplace revenue was also partly attributable to the 46% increase in the number of total subscribers from 14,766 as of June 30, 2011 to 21,544 as of June 30, 2012, which resulted in a $3.7 million increase in marketplace revenue during the six
months ended June 30, 2012 when compared to the six months ended June 30, 2011.

Media revenue increased to $9.3
million in the six months ended June 30, 2012 from $7.5 million in the six months ended June 30, 2011, an increase of $1.8 million, or 23%. This increase in media revenue was primarily attributable to the increase in the number of impressions sold
on a CPM or CPC basis which was primarily driven by an increase in overall advertiser demand for our display advertising inventory as we recognized an increase in monthly unique visitors from 13.4 million in the six months ended June 30, 2011 to
22.0 million in the six months ended June 30, 2012, a 64% increase. Although there is a correlation between numbers of monthly unique visitors and our media revenue, it is not a direct correlation. Therefore, and as in prior periods, the growth rate
in our monthly unique visitors has outpaced the growth rate of our media revenue.

headcount following the opening of our new facility in Denver in February 2011, and a $0.9 million increase in content license fees, hosting fees, and credit card fees due to higher subscription revenue. Cost of revenue increased to 16% of
revenue in the six months ended June 30, 2012 from 15% of revenue in the six months ended June 30, 2011, reflecting higher customer service-related costs in connection with the establishment of our new facility in Denver.

expenses, a $0.3 million increase in facilities expenses to support our headcount growth, and a $0.2 million increase in amortization of capitalized product development costs. Technology and development expenses decreased to 34% of revenue in
the six months ended June 30, 2012 from 41% of revenue in the six months ended June 30, 2011, reflecting the increase in our revenue. We expect our technology and development expenses to increase in dollar amount as we continue to invest in the

Sales and marketing expenses increased to $15.2 million in the six months ended June 30, 2012 from $7.3
million in the six months ended June 30, 2011, an increase of $7.9 million, or 109%. This increase was primarily the result of a $5.9 million increase in headcount and related benefits associated with the expansion of our sales personnel in our new
Denver facility, a $0.8 million increase in recruiting, depreciation, and facilities related expenses due to headcount growth, a $1.4 million increase in marketing and advertising expenses as we increased marketing activities for Trulia Mobile
Ads, partially offset by a $0.4 million decrease in external contractor fees as we converted third-party contractors to full time employees. Sales and marketing expenses increased to 52% of revenue in the six months ended June 30, 2012 from 45%
of revenue in the six months ended June 30, 2011. We expect sales and marketing expenses to increase in dollar amount as we hire additional employees to expand our sales force and to support our direct marketing initiatives.

Interest expense increased to $0.5 million in the six months ended June 30, 2012 from $41,000 in the six
months ended June 30, 2011. This increase was primarily the result of the incremental interest expense associated with the increased principal amount of our outstanding indebtedness during the six months ended June 30, 2012. Our indebtedness
increased from $3.3 million as of June 30, 2011 to $9.7 million as of June 30, 2012. We expect that our interest expense will continue to vary in future periods based on the terms specified and amounts borrowed under our existing credit facility.

Change in fair value of warrant liability was $0.3 million in the six months ended June 30, 2012, reflecting the increase in the fair value of our outstanding preferred stock warrants. In September 2011,
we issued preferred stock warrants in conjunction with establishing a new credit facility. Upon the exercise or expiration of the warrants, the conversion of the underlying shares of convertible stock, or the completion of our initial public
offering, the preferred stock warrant liability will be remeasured to fair value and any remaining liability will be reclassified to additional paid-in capital. We expect the fair value of the warrants to increase leading up to our initial public
offering but we do not expect any future charges following the completion of our initial public offering.

Revenue increased to $38.5 million in the year ended December 31, 2011 from $19.8 million in the year ended December 31, 2010, an increase of $18.7 million, or 95%. Marketplace revenue and media revenue
represented 58% and 42%, respectively, of total revenue in the year ended December 31, 2011, compared to 47% and 53%, respectively, of total revenue in the year ended December 31, 2010. The increase in marketplace revenue as a percentage
of total revenue was the result of significant growth in our subscription business, driven by increases in total subscribers and average monthly revenue per subscriber, which outpaced the growth of our advertising business.

Marketplace revenue increased to $22.3 million in the year ended December 31, 2011 from $9.4 million in the year ended December 31, 2010,
an increase of $12.9 million, or 138%. This increase in marketplace revenue was primarily attributable to the 67% increase in the number of total subscribers from 10,070 as of December 31, 2010 to 16,849 as of December 31, 2011. This
increase in total subscribers resulted in a $5.8 million increase in marketplace revenue during the year ended December 31, 2011 when compared to the year ended December 31, 2010. The increase in marketplace revenue was also partly attributable to a
38% increase in the average monthly revenue per subscriber from $80 in the year ended December 31, 2010 to $110 in the year ended December 31, 2011. This increase in average revenue per subscriber resulted in a $4.9 million increase in

Media revenue
increased to $16.3 million in the year ended December 31, 2011 from $10.4 million in the year ended December 31, 2010, an increase of $5.9 million, or 56%. This increase in media revenue was primarily the result of the increase in the number of
impressions sold on a CPM or CPC basis as we recognized an increase in overall advertiser demand for our display advertising inventory during the year ended December 31, 2011. These increases were primarily driven by an increase in our average
monthly unique visitors from 7.9 million in the year ended December 31, 2010 to 14.8 million in the year ended December 31, 2011, an increase of 86%. Although there is a correlation between monthly unique visitors and our media
revenue, it is not a direct correlation. Therefore, the growth rate in our monthly unique visitors has outpaced the growth rate of our media revenue.

Marketplace revenue increased to $9.4 million in the year ended December 31, 2010 from
$3.3 million in the year ended December 31, 2009, an increase of $6.1 million, or 185%. This increase in marketplace revenue was primarily attributable to the 116% increase in the number of total subscribers from 4,667 as of
December 31, 2009 to 10,070 as of December 31, 2010, which was driven by our Trulia Local Ads product launch in January 2010. This increase in total subscribers resulted in a $3.7 million increase in marketplace revenue during the
year ended December 31, 2010 when compared to the year ended December 31, 2009. The increase in marketplace revenue was also partly attributable to a 70% increase in the average monthly revenue per subscriber from $47 in the year ended
December 31, 2009 to $80 in the year ended December 31, 2010. This increase in average revenue per subscriber resulted in a $2.9 million increase in marketplace revenue during the year ended December 31, 2010 when compared to the year
